"Being able to run miles a day is a good measure of cardio endurance, but it's not the best measure of muscle endurance," says fitness expert Robert Dos Remedios, author of Cardio Strength Training. That's because running for distance primarily challenges your heart and lungs, not your legs. (Yes, your legs may feel tired, but your muscles aren't actually exhausted.) When you focus on muscular endurance--your ability to sustain resistance over time--you gain the strength to power through longer, more intense workouts, says Dos Remedios. The following test challenges both aspects, showing you how long your lungs and muscles can last before calling it quits.

Do all four moves back-to-back without rest. If you stop or can't do the move with proper form, that's the end of the test. Track your success through reps: On your first try, do 10 reps of each move. Wait two days, then repeat with 15 reps. Then test two days later with 24 reps.
