The bodybuilding group performed three sets of 10 reps each while the powerlifting group performed seven sets of three reps each. Interestingly, the powerlifting group produced greater strength as compared to the bodybuilding group. However, both routines produced a similar increase in hypertrophy of the biceps brachii.

It must be noted that the volume load was equal as it was impractical to carry long-term training with very heavy loads at volumes used in the study.

For more results, the study also researched on 19 college-aged men who were consistently lifting for a year and performed squats and bench presses. They were split into groups that trained in the heavy loading range of 8 to 12 reps per set. There was a total of seven exercises that worked on all the major muscles of the body and three sets per exercise were allotted.
