Similar Assertions

How many times you lift a weight affects what your body gets better at: lifting heavy weights a few times builds strength, lifting lighter weights many times builds endurance, and doing a middle amount builds muscle size.

Lifting heavy weights for just a few reps makes untrained young men much stronger than doing more reps with lighter weights, especially after 8 weeks of training.

Lifting very heavy weights a few times with long breaks builds more muscle and strength faster than lifting lighter weights many times with short breaks, when the total amount of lifting isn't the same.

Lifting lighter weights many times in a row helps untrained young men build more muscle endurance than lifting heavier weights fewer times. After 8 weeks, they can do more reps before getting tired.

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.
