I happened upon this… Researchers at Baylor University conducted a study to determine if high reps or low reps were better for building muscle SIZE quickly.
The scientists took a group of weight trainers and put them through a series of leg workouts. Half the group used heavy weights and lower reps – around 6 reps per set. The other half used lighter weights and completed 20 reps per set. After each workout the scientists took blood samples and muscle biopsies.
Here’s What They Discovered…
The test subjects that did low reps with heavy weights had 3X as much myostatin as the high rep subjects. Remember, more myostatin equals LESS muscle, so this increase is a very BAD THING if you want to get ripped and jacked quickly.
The scientists concluded that when it comes to training for maximum size, you would be smart to use lighter weights and higher reps.
Surely 30-10-30 falls under this banner. Possibly one of the reasons it delivers so well?
