Interval Training For Everyone

Circuit Training

Move through stations with timed intervals. 45 seconds work, 15 seconds to transition. The timer keeps everyone in sync and moving.

Rest Between Sets

Strength training? Use the timer for consistent rest periods. 90 seconds between heavy sets. 60 seconds for hypertrophy. Never guess your rest again.
