Most bodybuilders would love to be called a powerlifter, but the vice versa is not true. I have observed this over the years between bodybuilders vs powerlifters. If you say to a bodybuilder that he looks pretty big and strong like a powerlifter, he generally takes it as a compliment. But, try saying to a powerlifter that you are quite muscular and look like a bodybuilder, the look he gives you is as if you are the reason for him not improving his squat.

A powerlifter in most cases is always ready with the explanation of how bodybuilders are non-functional, and how strength is should be the only goal, in addition to how bodybuilding is not even a sport.

bodybuilders vs powerlifters

Bodybuilding Vs Powerlifting, technical is two distinct sports, with very specific requirements. In Powerlifting you have primarily three basic movements, squat, deadlift & the bench press. The aim of the lifter is simply one, lift the maximum weight using the right technique. That’s it. A powerlifter’s entire training, nutrition and recovery methods are geared towards these three basic lifts, and how to increase the poundage they can lift.

Bodybuilding, on the other hand, is more of an art, as the aim of the bodybuilder is to build maximum muscularity & definition, with the right size & symmetry, in order to obtain maximum points by the judges, who judge the athlete by a series of poses he/she displays on the stage. There are a lot of nutritional manipulations involved in bodybuilding, like salt and water manipulation, carb depletion & loading, etc. None of these techniques are used in powerlifting.

Now, had bodybuilding been just lifting heavy weights, then all powerlifters would have also looked like bodybuilders. But in the case of powerlifting, the physique in terms of symmetry and proportion is far from being attractive. Most top powerlifters are big fat, but muscular giants.

Tom Platz was known for having the biggest legs in the history of bodybuilding. In 1993 he had a squatting competition with the legendary “Fred Hatfield” (also known as “Dr. Squat” and is the first man in the history to squat over 1000 lbs). During the competition of bodybuilders vs powerlifters, Fred lifted 855 lbs max to Tom’s 765 lbs for a single rep. However, when it came to muscle endurance Tom did a squat with 525 lbs for 23 reps as compared to Fred’s 11. This showed that bodybuilders not only have strength but also phenomenal muscle endurance.

bodybuilders vs powerlifters

One reason which is common between(bodybuilders vs powerlifters) the two sports is strength. Using the basic principles of exercise physiology, as per the principle of progressive overload, as you keep lifting heavier, you keep getting stronger. But when it comes to the slightly advanced phase of training and increasing muscularity, then just lifting heavy won’t do. We have seen a number of powerlifters around the world who have tremendous strength and power but are nowhere close to the bodybuilders when it comes to muscularity.

However, strength remains the base of the workout. You cannot build a 20-inch arm with a 20 lb dumbbell.

One of the most important concepts of lifting is “Time Under Tension”. The more the time for which your muscle is under tension greater will be the muscle growth. But who can put more tension on the muscle than powerlifters? Then what is lacking? What also matters is not just time under tension but the intensity and frequency of tension.

One of the reasons for a greater endurance is due to the increased number of slow-twitch fibers or Type I muscle fibers which have a limited ability to produce force, an extreme example would be a distance runner. However, as per research, these fibers also undergo hypertrophy or increase in size, though their hypertrophy capacity is around 50% less than the fast-twitch muscle fibers. These slow-twitch muscle fibers are more in number in bodybuilders vs powerlifters. Bret Contreras showed that slow-twitch muscle fibers can affect hypertrophy without having much effect on muscle strength.

Author and world-record-holding powerlifter, Greg Nuckols, suggests that the maximal force production for a given area of Type I fibres is almost exactly the same as the maximal force production for a given area of Type II fibres. Type II fibres simply reach maximal force output sooner, making them better for power-dependent activities like sprinting or jumping. Powerlifting, though (contrary to what the name may lead you to believe), is NOT a power-dependent sport. Power output actually peaks around 30-60%1rm and is quite low with maximal loads. All of which means, fiber type distribution doesn’t influence how much you can lift very much at all.

Acc. to Bret Contreras & Brad Schoenfeld (https://bit.ly/30qOy6H), the stronger does not necessarily mean bigger, and bigger does not necessarily mean stronger.

However, there are some significant differences between bodybuilders vs powerlifters which explain why and how bodybuilders are more muscular:

  1. Rep range & volume – powerlifters train within a rep range of 1-5 and bodybuilders perform a rep range of 6-12. At this high rep range, the type I fibers undergo greater hypertrophy due to greater time under tension which is not the case with powerlifters. Also because total reps are more, more is the amount of total poundage lifted.

What this means is that bodybuilders train with a lot of volumes. A powerlifter may lift much more weight during a single set, but an overall weight lifted in the total workout is quite high in case of a bodybuilder, because of the sheer higher number of sets and reps they do. Bret Contreras gave an example of the same, when he said (https://bit.ly/30qOy6H), “Let’s say a bodybuilder performs a bench press routine consisting of 225 x 12, 275 x 10, 315 x 8, and 335 x 6, while a powerlifter does 315 x 5, 365 x 3, 405 x 1, and 415 x 1. Under this scenario, the bodybuilder lifted 9,980 total pounds while the powerlifter lifted 3,490 total pounds.

Assuming 2 seconds per repetition, the bodybuilder accumulated 72 seconds under tension while the powerlifter accumulated 20 seconds under tension – a significant difference in bodybuilders vs powerlifters!

When volume comes into play, it is inversely proportional to intensity. To go high in volume you cannot work at intensities of a powerlifter. If you try higher repetition with your 85-90% 1RM, then you risk getting injured.

bodybuilders vs powerlifters

In a 2014 study in the Journal of Strength & Conditioning Research, by a team of leading researchers like SchoenfeldRatamess, Contreras, etc. (https://bit.ly/3d2MJlp), suggested that, although muscle hypertrophy can be attained through a wide range of resistance training programs, the principle of specificity, which states that adaptations are specific to the nature of the applied stimulus, dictates that some programs will promote greater hypertrophy than others.

The researchers investigated muscular adaptations to a volume-equated bodybuilding-type training program vs. a powerlifting-type routine(bodybuilders vs powerlifters) in well-trained subjects. Seventeen young men were randomly assigned to either a hypertrophy-type resistance training group that performed 3 sets of 10 repetition maximum (RM) with 90 seconds rest or a strength-type resistance training (ST) group that performed 7 sets of 3RM with a 3-minute rest interval. After 8 weeks, no significant differences were noted in muscle thickness of the biceps brachii. Significant strength differences were found in favor of ST for the 1RM bench press, and a trend was found for greater increases in the 1RM squat.

In conclusion, this study showed that both bodybuilding and powerlifting-type training promote similar increases in muscular size, but powerlifting-type training is superior for enhancing maximal strength.

Now, looking at this study, it looks that the rep range doesn’t matter for hypertrophy. But Schoenfeld made some glaring observations in this study. First, it is important to point out that the total training time in the ST group was 70 minutes while that of the HT group was 17 minutes. So, from a time-efficiency standpoint, the bodybuilding-type training produced similar hypertrophy (as well as nearly similar strength increases) in about a quarter of the time as the powerlifting routine. Moreover, exit interviews revealed that those in the ST group were fried by the end of the study. Almost all of them complained of sore joints and general fatigue, and the two dropouts from this group were because of joint-related injury. On the other hand, the HT group all felt they could have worked substantially harder and done more volume.

Schoenfeld says, “While mechanistically it seems that it does not matter whether heavy or moderately heavyweights are used for hypertrophy, from an application standpoint it simply isn’t practical to train constantly with the volumes used in this study on multiple body parts. The grinding on the joints and the taxation of the neural system that is involved with the repeated performance of very heavy loads ultimately has a negative impact on the lifter; I am certain that if we had continued this program for any longer, most of those in the ST group would have been overtrained and seen performance decrements. If nothing else, these findings reinforce the importance of periodizing programs so that cycles of deloading are interspersed with very heavy loading protocols.

The study indicates that the best approach to building muscle is to perform a combination of heavy and moderately heavy loads. The “hypertrophy range” is applicable from the standpoint that it allows the performance of a greater amount of volume without overtaxing the body’s resources. Adding in loads in the 1-5 RM range can enhance strength (which ultimately allows the use of heavier loads during moderate rep lifting) as well as providing a potent hypertrophic stimulus.”

bodybuilders vs powerlifters

In a 2010 study in the journal Plos One, A Canadian research team led by, Nicholas Burd (https://bit.ly/2HM8hXQ), determined the effect of resistance exercise intensity (% 1 repetition maximum—1RM) and volume on muscle protein synthesis, anabolic signaling, and myogenic gene expression. For the study, 15 men performed 4 sets of unilateral leg extension exercise at different exercise loads or volume. The study showed that low-load high volume resistance exercise is more effective in inducing acute muscle anabolism than high-load low volume or work matched resistance exercise modes. That’s why bodybuilding style workouts induce greater hypertrophy.

  1. Bodybuilders work for the pump. At the higher rep, range muscles get pumped more which in studies have shown to be an important factor in muscle development. As the muscle gets pumped or more blood is sent into a particular muscle. Now, this increase in size is perceived as a threat to the muscle cell to which it responds by increasing size and increasing the total number of satellite cells sent to the muscle. Also, there is a greater increase in muscle protein synthesis.
  2. Bodybuilders train, in most cases, for momentary muscle failure, in almost every set. Failure is the stage, where you cannot perform another rep on your own. Powerlifters, on the other hand, never train to failure, as it can negatively affect their form.

  1. Bodybuilders also incorporate a number of isolation or single-joint movements along with compound or multi-joint movements. Powerlifters, on the other hand, stick only to basic compound lift like bench press, squats, deadlifts, military press, etc. Bret Contreras says (https://bit.ly/34hurcc), “large muscles like quads, pectorals, deltoids, and lats are made up of thousands of thread-like fibers that have multiple different attachment sites. These fibers are sometimes compartmentalized and/or supplied by different nerves. Thus muscles don’t always get worked evenly throughout the entire length during exercises as a certain exercise may stress a region closer to the origin or insertion. Only by training from multiple angles with a variety of exercises can you fully stimulate all of these fibers and thus maximize the development.
  2. One of the most important parts of the movement is not just the concentric movement but also the eccentric movement. More the number of reps you do more will be the eccentric movement, and more the muscle damage thus greater hypertrophy.
  3. Bodybuilders while performing a rep, execute it in a very slow and controlled manner, thus increasing the time under tension. Whereas powerlifters need to lift maximum weight and can play along with their form a bit. Also, a bodybuilder never locks out his joint in any exercise thus keeping constant tension on the muscle.
  4. It is well known that the higher the intensity of the workout greater hit the central nervous system takes. Powerlifters care just about lifting as heavy as possible. Bret and Brad say (https://bit.ly/34hurcc), “powerlifters try to involve as many muscles as possible to generate optimum force. for example, during the bench press, a powerlifter attempts to maximize leg drive along with pecs, lats, anterior delts, and triceps contribute to lift the heaviest weight. They’re more concerned with optimal mechanics than muscle activation. While the powerlifter method is great for total body stimulation, the bodybuilding method really hammers a particular area and might induce more damage and a greater pump while reducing overload to the central nervous system.”
  5. Different variations used in the workout of bodybuilders vs powerlifters like negatives, forced reps, supersets, burns, rest-pause sets, tri-sets, etc deliver additional hypertrophy stimulating signals that can lead to greater muscle growth.
  6. Another method to enhance hypertrophy is to reduce the time between sets. Bodybuilders take very short rest may be up to 60-100 sec as compared to up to 5 min taken by powerlifters. Short rest intervals lead to an increased anabolic hormonal response in the body says, William J. Kraemer.

In a 2010 study in the Journal of Strength and Conditioning Research, by a research team led by P. Gentil (https://bit.ly/3js8BsM), investigated the effects of differences between set rest interval durations on muscle strength after 12 weeks of resistance training. 34 non-resistance trained college-aged men were assigned to 2 groups. Both groups trained twice a week and performed the same exercises with 2 sets of 8 to 12 repetitions until volitional fatigue. One group used short-rest intervals (SR) with a work-rest ratio of approximately 1:3; the other used long-rest intervals (LR) with a work-rest ratio of approximately 1:6. Leg press and bench press 1 repetition maximum (1RMwere measured at baseline and after the end of the training period.

The results did not reveal significant differences between SR and LR for the bench press or leg press 1RM. The data suggest that gains in maximum strength in non-trained men are not dependent on the length of the rest interval between sets. But, what needs to be noted is that the study was done on non-trained individuals or beginners. So, for beginners, the rest intervals do not matter. Also, the researchers conclude by saying that, “the results are limited to muscle strength, and the manipulation of rest intervals may interfere with other adaptations such as muscle hypertrophy, power, and endurance.”

In an earlier 2005 study in the Journal of Strength and Conditioning Research, by a Finnish research team, led by J.P. Ahtiainen (https://bit.ly/3cXQnNt), studied acute and long-term hormonal and neuromuscular adaptations to hypertrophic strength training in 13 strength-trained men. The study comprised a 6-month hypertrophic strength-training period including 2 separate 3-month training periods, a training protocol of short rest (SR, 2 minutes) as compared with long rest (LR, 5 minutes) between the sets. According to the study, both 3-month training periods performed with either the longer or the shorter rest periods between the sets resulted in similar gains in muscle mass and strength. No statistically significant changes were observed in basal hormone concentrations or in the profiles of acute hormonal responses during the entire 6-month experimental training period.

  1. Bodybuilders give ample time for recovery to each muscle. Powerlifters hit the same muscles almost every day because of the limited range of exercises they do. This leads to cumulative fatigue overtime and decreased muscle hypertrophy.
