Question

If you had a 30-pound barbell at home and you wanted to compare your muscular endurance to your younger brother's, which method would be the BEST to use?

Answer 1

Have both of you take a turn holding up the barbell above your head for as long as you can, using a stopwatch to clock the time.

Answer 2

They time how long each can hold it up above their heads for, then compare the times. The longest time has the most endurance.
