Powerlifters are athletes that place a large focus on absolute strength. They generally train using lower repetitions but utilize a high volume of compound movements (Squats, Deadlifts and Bench Press), with lengthy periods of time between working sets. They do an exhaustive amount of training using competition style lifts and much of their increases in strength are due to better efficiency in recruiting their Central Nervous Systems.
While many powerlifters are happy to build hypertrophy, they generally aim to get as strong as they possibly can, while not increasing their muscle size.
Powerlifters also add complementary “assistance” exercises to their programs, however these are done for the sole purpose of increasing their 1RM in the “big three” lifts.
While many power lifters maintain an adequate level of fitness, this is considered very secondary as many are concerned about doing anything to compromise pure strength.
