For pulley rows, on the other hand, my best pump is produced between reps 10 and 12, when I have 400 pounds on the stack. Always consult with a qualified healthcare professional prior to beginning any diet or exercise program or taking any dietary supplement. To build muscle, you need to maximize muscle protein synthesis and inhibit protein breakdown. Moderately heavy weight provides a good balance between the two, meaning your trained muscle will get an optimal combination of growth stimuli. If you’re looking for an edge to build as much muscle as possible, then most of your training would be performed within this rep zone. Next Election in 2024. My recommendation is to shoot for failure (the point at which you don’t have enough strength left to perform another rep) around 8 reps to maximize muscle growth. If you can’t do six clean reps, it’s too heavy; if you can easily do 12 clean reps, it’s too light. And as said by bodybuilder Ronnie Coleman: Since Jan 3, 2013. The following is an alphabetical list of members of the United States House of Representatives from the commonwealth of Massachusetts.For chronological tables of members of both houses of the United States Congress from the state (through the present day), see United States Congressional Delegations from Massachusetts.The list of names should be complete, but other data may be incomplete. Isolation Movements. Barbell Curl. What do you think of doing 10 reps per set for mass? The slower the muscle fatigues, the lower it's neuromuscular efficiency, and the greater the number of slow twitch fibers. The studies above have provided us with a clear way to optimize this tension, to squeeze the most growth from every set. That's a huge difference, which would result in a huge difference in weight used and probably a big difference in the progress the trainee made. In other words, the type of load – or, how heavy the weight is – is the primary driving force behind the building of muscle mass. And the reserved internet researcher might regurgitate some “facts” he was told on a bodybuilding form. This means that the muscles are not receiving enough stimulation and time under tension to trigger growth optimally. Yes, once again, to add muscle, you must work out harder, not longer. I don’t believe in doing any of the traditional powerlifting or Olympic lifting exercises for more than 6-8 reps unless you have really solid technique and at least a year of experience. The average amount of muscle mass gained in the high rep group was 2.2 pounds (1 kilogram), compared with 3.5 pounds (1.6 kilograms) in the low rep group. This makes sense, because there's an inverse relationship between reps and load: If you do more reps, … There is some scientific evidence out there to support this theory. Again, if you look at the 1RM percentage chart: 75% of 1RM = 10 reps, “At 1 h post-exercise at 60-90% 1 RM, p70s6K phosphorylation predicted the rate of MPS at 1-2 h post-exercise in the young but not in the old. If you’re looking for an edge to build as much muscle as possible, then most of your training would be performed within this rep zone. However, to maximize size, the scientific literature provides us with an optimal range to work within, most of the time. Compound Dumbbell Movements. The traditional method for building muscle mass, for both men and women alike, is to lift heavier weights and increase the amount of weight over time. Plus, I’m going to provide some solid scientific studies on this subject. For example, if you bench-pressed 315 for 12 reps, you'd rest for 60 seconds and then try your best to hit 6 reps, i.e., half the number of reps you were able to do on the first set. Let’s take a look at a couple more studies. For a set of 8 - 12 reps, most of them have a time under load of about 16 - 36 seconds, at most. The chart that follows will help you find a good estimate, but before you get to that – here’s an interesting study I want to share with you. Hypertrophy Studies . High Reps vs Low Reps for Muscle Growth. For example, if you bench-pressed 315 for 12 reps, you'd rest for 60 seconds and then try your best to hit 6 reps, i.e., half the number of reps you were able to do on the first set. And lifting outrageously heavy weights that induce trembling arms and bloodshot eyes is not the catalyst, either. Slow twitch (more endurance oriented) respond best with a tension time of 90 - 120 seconds, while a mixture of the two does well with a time under load of approximately 50 - 90 seconds. Once relative intensity reaches 80% 1RM, it appears that maximal growth is attained. Rep ranges are often categorised into 3 main “loading zones” and each are quite well accepted and validated by studies to produce the following primary outcomes. Bentover row. The Perfect Rep range for muscle bulk and hypertrophy is 6 to 12 repetitions per set with upper body performing best between 6-9 reps and lower body at higher 8-12 reps per set.. A fast recap of intensity principle: As you know muscle hypertrophy depends on training intensity.And to build muscle mass you need to train in the range of 65 to 85% of your one rep maximum. Heavier weights in the low to moderate rep range, on the other hand, has long been accepted as the best way to maximize muscle growth. So why does training in this rep range produce the greatest gains in size? This means that you have to use a weight with which you can squeeze six to 12 clean reps. High (light weight): 15+ reps are within the “Endurance Range”, used primarily to increase muscular endurance. Neither of these sources are very helpful. Overall volume of work will determine, chemically, how much energy your muscle cells require. You can see from the graph below how there’s a gradual increase in growth stimuli, which tapers off after 75% of the 1RM. Heavy weights mean less metabolic stress, and light weights mean less mechanical tension. The average amount of muscle mass gained in the high rep group was 2.2 pounds (1 kilogram), compared with 3.5 pounds (1.6 kilograms) in the low rep group. A study in 2009 conducted by Kumar et al. Since I starting training my bench press has gone from 45 pounds to 275 for a couple reps. While it may not be optimal, you can still build muscle in the 4-6-rep range. Examples: Squats, bench press, overhead press, bent over rows. That is, multiply the weight you're doing by the number of reps and sets you complete (e.g. Group one did 3 sets of 8-12 reps to failure with a heavy(ish) weight. Lower reps tend to be ideal for the bigger compound lifts, giving us loose rep range recommendations for our five big hypertrophy lifts of, say: Deadlifts: 4–10 reps per set. There are some problems with this general thinking. This is a very demanding technique, so don’t do more than one or two sets of this technique per exercise. The time under tension or number of reps per set that is appropriate for you is also affected by your muscle fiber make up and your neuromuscular efficiency. Overall, I've put on over 40 pounds of muscle. The biased muscled meathead at the local gym, occupied with moving as much weight as possible in an unwitting move to feed his ego will always tell you to “go heavy”. If you’re out to train your muscles so that they perform better over an extended period – think boxer or marathon runner – then this is where you’d do most of your training. You will find two things. Take a look at the chart below to see how 1RM percentages relate to repetitions: 100% of 1RM = 1 rep95% of 1RM = 2 reps93% of 1RM = 3 reps90% of 1RM = 4 reps87% of 1RM = 5 reps85% of 1RM = 6 reps83% of 1RM = 7 reps80% of 1RM = 8 reps77% of 1RM = 9 reps75% of 1RM = 10 reps67% of 1RM = 12 reps65% of 1RM = 15 reps. As you can see, 75% of your one rep max works out at around 10 reps. That means, if you reach failure on the 10th rep of bench pressing 80kg, then 80kg is 75% of your 1 rep max. If you are looking to increase size or better build some muscle mass, you should perform 4 – 6 repetitions at 80 – 85% of your 1RM or 6 – 12 repetitions at 65 – 80% of your 1RM. The onset of fatigue from moving heavy loads will diminish workout intensity and effort, resulting in not only less reps and sets per workout, but a reduction in quality repetitions. Heavier weights in the low to moderate rep range, on the other hand, has long been accepted as the best way to maximize muscle growth. All of the rep ranges mentioned will cause muscle growth to occur, just in different ways and to various degrees. The bottom line is that most of your training should be done within 8 – 10 reps as this has been found to be the best rep range for size. If you’re looking for an edge to build as much muscle as possible, then most of your training would be performed within this rep zone. Lifting weights creates a level of tension across your muscle fibres. Conventional wisdom has us convinced that high reps and light weights builds muscle endurance and makes little contribution to gains in muscle mass. Accessory movements like chest flyes, shoulder lateral raises, front raises, and cable grips should be treated as "pump" exercises. The version that works best for size is using 75-80%, generally a weight you can get 6 or 7 reps with. Maximum protein synthesis has been shown to occur between 70-85% of your one rep max (1RM). This is what makes the 1-6 loading scheme an amazingly effective muscle-growth method. Preparatory phase 1. The main mistake people make when using the 1-6 principle is not understanding that the work sets, the sets that are the most important, are the sets of 6. Doing 1-6 properly: weight used for the sets of 1 rep. Massachusetts’s senators are: Senior Senator Elizabeth Warren. This is where intuition comes into the mix. 6 – 12 reps are within the “Hypertrophy Range”, used primarily to build muscle mass. 6 – 12 reps are within the “Hypertrophy Range”, used primarily to build muscle mass. An example from my personal workout routine is that I’ll always start with a big, compound movement of around 4 sets of 4-6 reps. All of the exercises after that, I’ll use a rep scheme of around 8-15 reps for the best of both worlds. If I wanted to get REAL big shouldn't I do 4 sets of 4-6 reps of something like 22kg to get stronger which would mean I could do 19kg on each arm for 4 sets of 6-8 reps? Mike usually recommended 6 to 10 reps per set. Overhead … The final three workouts of the week are based on higher reps. I was just thinking about this. The reason that the growth response is lower at 90% of 1RM is because the weight is just too heavy. To help you understand how load and reps impact growth, you need to understand something called your one rep max or 1RM. Hamstring Curl. I tried sets of 3-4, but it was too fatiguing, and enough volume was nearly impossible to achieve. As you can see from these studies, there’s no single best number of reps to build muscle, just like there’s no single best exercise, or single best protein source, for building muscle, either. Type 2, known as “fast twitch” fibers, respond better to heavy weights / low reps. With that said, there is a narrow rep range to work within most of the time to optimize when training for gains in muscle size. As required by the Massachusetts Constitution, the House may not adjourn itself for more than 2 days, meeting year-round in … If I wanted to get REAL big shouldn't I do 4 sets of 4-6 reps of something like 22kg to get stronger which would mean I could do 19kg on each arm for 4 sets of 6-8 reps? 1RM – One repetition maximum, is the maximum amount of weight a person is able to lift for a single repetition. All other variables – rep tempo and rest between sets – were kept the same. They also ignore the fact that the ideal time under tension (or number of reps), most likely varies from muscle to muscle within the same individual. You may want to go heavy with 5 reps or lighten up and work in the 12+ rep range from time to time. All they know is what's known as Time Under Tension (TUT), or Time Under Load (TUL). The first three workouts are based on heavy compound movements. Muscle Mass for slow twitch fibers - 12 - 20 or more reps per set such as thighs and calves, and for some this still includes the outdated notion of high reps for definition. Growth stimuli from resistance exercise is caused by a combination of mechanical tension and fatigue induced metabolic stress, and to some degree, muscle damage. If you can’t do six clean reps, it’s too heavy; if you can easily do 12 clean reps, it’s too light. But that’s not the case, because very heavy loads don’t allow for much time under tension, or for the accumulation of metabolic stress. Minimal metabolic stress is seen in training routines involving very heavy loads. As you can see, most trainees today use load times well below the most effective tension times for inducing a positive response in their body. If you choose to lift a lot of heavy weight, the load is high, and the reps will be low. Eventually, the 8 - 12 reps were always prescribed, and the time under load fell by the way side. What’s also interesting to note from this study is the wide range where muscle growth peaks. This was a study that looked at data from many studies to see how weight selection affects muscle growth. 2. Is 10 reps to high for mass? The rep range you have to follow actually tells you the amount of weight you have to lift. I’d appreciate any advice, thanks. "Bigger" isolation movements like dumbbell bench presses and shoulder presses require going pretty heavy, and keeping reps between 6 and 10 makes sense. When your muscles adapt and grow from sets and reps of resistance weight training, they aren’t responding to numbers, they’re responding to tension. Junior Senator Edward “Ed” Markey. Lats The lats are generally of mixed composition and thus respond best to medium reps. You can’t go wrong sticking with an average of 6-8 reps per set on lat work. All rights reserved. 4-6 Reps For Mass So I've been doing all my lifts at 4, 4, 6 ,6 except for legs. Democrat. If you are just starting out, max out at 6 reps and then build-up to the mid-range. Unfortunately, it was the time under load recommendation of 48 - 72 seconds per set that was the reason the 8 - 12 reps were effective. I’ve been training using 6 reps for mass for ages now and even though it’s helped me to put on a lot of size I think I may have plateau’d so am thinking of changing my rep range. This is a very important part of this concept that has gotten lost over the years. 6-8 is really the best rep range for building strength imo after 2-3 years of lifting. TUT and TUL can be used interchangeably. Best reps for muscle strength: low reps with heavy weights, best to stick within the 3 – 8 rep range. This is a very effective strategy in terms of keeping focused because you're trying to essentially break three PR's: High-reps, for example, will have a different meaning for a powerlifter compared to a bodybuilder or a long-distance runner. In addition, they compound the problem by trying to make up for this by adding more and more sets. Studies show that training within this moderate range with a weight you can handle with good form is best for building mass. In this study the researchers found that the growth response also peaked with weights that were around 75% of 1RM. This is a vital fact of exercise physiology to understand if you wish to optimize your progress. But before we get into that, let’s talk about another contributor to hypertrophy – metabolic stress. Mike advocated rep speeds that took about 10 seconds to complete each rep. For 6 reps, that's 60 seconds of TUL. That’s not to say you should only ever use this rep range. Which group do you think built the most muscle? Skeletal muscles are made up of a mixture of two main types of muscle fibres. | Age-related differences in the dose–response relationship of muscle protein synthesis to resistance exercise in young and old men | The Journal of Physiology | 10.1113/jphysiol.2008.164483 (, | The Role of Resistance Exercise Intensity on Muscle Fibre Adaptations Andrew C. Fry Human Performance Laboratories, The University of Memphis, Memphis, Tennessee, USA (, Bodybuilding Breakfast Ideas (6 of the Best), Relentlessgains.com - Build Muscle, Get Lean, Get Strong. 5. First, muscles don't count reps, so these numbers could be completely different for someone who takes 10 seconds to complete one rep, compared to someone who takes 2 seconds for each rep. You need to use enough tension to keep your body from using its aerobic power, but not so much tension that you don't keep the muscle under tension long enough to elicit a positive anaerobic reaction. Of course, there is plenty of overlap (a lot, actually) in result outcomes across these ranges, as you can see from this visual illustration. 6 – 12 reps are within the “Hypertrophy Range”, used primarily to build muscle mass. Bench Press. Do 6 reps with that weight, then rack the bar and rest for 15-20 seconds, and then try to complete 4 more reps with the same weight. MyLegislature. However, training with moderately heavy loads within the 8 – 12 rep range taken close to failure will recruit ALL muscle fibers, fairly equality – Type 1, Type 2a and Type 2b – so there’s no need for fiber specific training. For example, you can build a lot of strength from training in the mid “hypertrophy range”, and you can build a lot of muscle from training in the low “strength range”. The amount of contradicting opinions on this question is staggering. “Although many training variables contribute to the performance, cellular and molecular adaptations to resistance exercise, relative intensity (% 1 repetition maximum [%1RM]) appears to be an important factor.”, “Examination suggest that there may be a threshold for optimal growth responses. I have always been confused with these recommendations, essentially there are two distinct adaptations when it comes to hypertrophy (muscle growth). The only way to accurately measure progress, and to ensure that you are keeping the muscle under adequate tension, is to use seconds to measure time under tension, and not number of repetitions. Current Term Ends Jan 3, 2021. If the weight is too light, you will be able to perform lots of repetitions, but the tension on the muscle will be minimal and not enough to stimulate significant growth. But high weight and low reps is not the best approach for building muscle. These are vital factors when determining the appropriate number of reps, or time under tension, that is needed for a body part to induce optimal (or any) results from your training. The amount of tension or load placed on the muscle, and the amount of time the muscle can maintain that tension are inversely proportional. There’s also some hypertrophy in these workouts. I was just thinking about this. Had the study lasted longer, or the number of subjects been larger, the difference in results between the two groups may have become large enough to cross the statistically significant threshold. Best reps for muscle mass: a combination of low reps and high reps. It would make sense to assume that lighter, high rep sets would favor growth of type 1 fibers, and that heavier, low rep sets would favor growth of type 2 fibers. This is where the 8 - 12 repetition guide came from. Remember, it’s the muscular TENSION produced in this range that’s important. The proven rep range for increasing strength is one to six reps. Let’s get one thing straight – feeling the “burn” from very high rep training does not cause growth. Compound Barbell Movements. Barry holds a Level 2 Gym Instructing Certificate, but his expert knowledge comes from over 20 years of obsessive science based research on building muscle optimally. Here’s why…. 6. This weight causes the nervous system to fatigue first, not the muscle fibres. Squat. “How many reps should you do to build muscle” or whether you should train with “high reps vs low reps to build muscle” is a common question I get asked. Use MyLegislature to follow bills, hearings, and legislators that interest you. However, the way most people perform reps, that's only about 12 - 18 seconds. I found 5 reps to be optimal, but as I started adding weight to pull ups, … The lower rep ranges 1-6 build mass and strength were the 8-12 is the balance between good strength and definition gains. This will optimise your sets for growth by providing optimal levels of metabolic stress and mechanical tension, while also allowing you to get the best quality work in, as this load allows you to exercise muscle groups with the greatest range of motion while maintaining good form throughout each set. Their findings concluded that growth stimulation peaks around 80% 1RM, very similar to the first study, and that there is in fact a threshold where the growth response is optimized. The lower body tends to have slightly more type 1 fibers compared to the upper body. Training with moderately heavy weights within the 8 – 12 rep range is where metabolic stress “kicks-in”, which is the exercise induced accumulation of metabolites within the muscle. While weight training to add muscle mass, muscle tension beyond a certain point, and maintained within a certain time frame (without moving into aerobic territory), causes the chemical reactions in the muscle that triggers the adaptive response. For example, the rep range to develop size is six to 12 reps. They found that the anabolic response (muscle building) increased by: 30% after training with weights that were 20% of 1RM40% after training with weights that were 40% of 1RM100% after training with weights that were 60% of 1RM130% after training with weights that were 75% of 1RM100% after training with weights that were 90% of 1RM. These very heavy weights provide the stimulus needed to grow stronger. The results suggest that in the post-absorptive state: (i) MPS (Muscle Protein Synthesis) is dose dependant on intensity rising to a plateau at 60-90% 1 RM“, “Rather than the hyperbolic relationship we postulated, they show a sigmoidal dose–response relationship of myofibrillar protein synthesis to exercise intensity, with little increase from 20 to 40% 1 RM, then a bigger rise at 60% of 1 RM, with no significant further increase up to 90% 1 RM.“. Bodybuilding.com℠ and BodySpace® are trademarks of Bodybuilding.com. I’ve extensively researched this subject and from my experience and study can confirm that you should be training within the 6 – 12 rep (8- 10 being most optimal) range most of the time if you want to maximize gains in muscle growth. The Massachusetts House of Representatives is comprised of 160 members, each representing a district of approximately 40,000 people. For example, the rep range to develop size is six to 12 reps. 5777 N Meeker Ave, Boise, ID 83713-1520 USA. They fatigue easily and are the most powerful. With enough rest before the next workout, this allows the muscle to over compensate and grow larger and stronger. People then got the notion that Heavy Duty was about lifting extremely heavy weights but in truth this was not the case. Or switch to some lighter, high rep work for a couple of weeks to improve muscular endurance and enjoy a better “pump”. And the rep speed of the majority of trainees is about 1 second up and 1 second down. There may be some benefit to utilizing rep ranges across the entire spectrum, such as increasing strength, or endurance, but for building muscle, most of your training should be within the 8 – 10 “hypertrophy zone”. Muscle growth can be achieved using a variety of rep ranges. All they end up doing is cutting into the muscles recovery time and never allowing it to over compensate and grow larger and stronger. Around 85% of your training should be within this moderate intensity loading zone. The aforementioned 8 – 12 rep range gives the best combination of muscle fiber recruitment, metabolic stress, mechanical tension, and time under tension for the goal of muscular hypertrophy. Muscle Mass for slow twitch fibers - 12 - 20 or more reps per set such as thighs and calves, and for some this still includes the outdated notion of high reps for definition. Do low reps build muscle, then? Say I wanted to get real big, I would do 4 sets of 6-8 reps. Say I was doing 17kg on each arm for bicep curls. Representatives. For example, switch to heavy, low rep work for a week or two, a couple of times a year to build strength. As we can see from this information, the peak of muscle growth occurs when training with a weight that is around 75% of our 1RM. Each repetition took 6 seconds to complete for a total rep time of 48 - 72 seconds for the entire set. | Age-related differences in the dose–response relationship of muscle protein synthesis to resistance exercise in young and old men | The Journal of Physiology | 10.1113/jphysiol.2008.164483 (source). Best Rep Range by Exercise. If you reach failure at the 8th rep, then whatever weight you’re using for that exercise would be 80% of your 1 rep max. Your muscles are made up of around 50% type 1 and 50% type 2 fibers, give or take. So, back to the question – what rep range should you really be training in to maximize muscle growth? The truth is, muscle growth can be achieved by training within more than one rep range, there’s no “magic” or “perfect” single rep for building muscle. It’s just that you’ll get more of one outcome over the other, depending on which range you train within. (Journal of Applied Physiology) measured the fluctuations in muscle protein synthesis after weight training. The optimal number of reps per set to achieve maximum muscle growth is a fiercely debated and disputed subject amongst the bodybuilding community. Excluding such things as mental effort, fast twitch fibers respond best with a tension time of approximately 40 - 50 seconds. If you choose to lift a very light weight, the load is low, and the reps will be high. When studies were done that showed 8 - 12 repetitions was the optimal number of reps in a set for most people, the accepted cadence was 2 seconds for the raising (positive) part of the rep and 4 seconds (negative) for the lowering of the weight.
