Lisa and Rachel want to determine their muscular endurance, but they don't have access to a gym or any weight-lifting equipment. What can they use?

The calisthenic method measures muscular endurance using body-weight exercises, such as push-ups or sit-ups, so no gym or weight-lifting equipment is needed. The maxing-out and percent-of-1-RM methods depend on lifting weights to assess strength, while the absolute method is not the appropriate equipment-free endurance method.
