Similar Assertions

If a young, healthy man lifts weights for 8 weeks, his muscles will likely get bigger—by about 6%, give or take a little.

Lifting weights with fewer reps (3-11) builds more muscle than doing lots of reps (20-28) in young guys new to training, especially after 8 weeks.

When untrained young men lift weights until they can't anymore three times a week for six weeks, and they do the same total amount of work, their muscles grow about the same amount whether they lift heavy or light weights.

If you're already fit and lift weights, doing 5 to 20 sets of exercises for each muscle group every week won't make you grow bigger muscles any more or less than any other number in that range.

Even though guys doing drop sets did only one set instead of three, their muscles grew just as much or more than those who did three sets.
