CrossFit AMRAP Timer
AMRAP (As Many Rounds As Possible) is one of CrossFit's foundational workout formats. You set a fixed time window — 7, 10, 12, 15, or 20 minutes are most common — and complete as many full rounds of the prescribed circuit as possible within that window. Score is total rounds plus any additional reps in a partial final round. The 10-minute default is a versatile AMRAP duration: long enough to produce significant metabolic conditioning, short enough to allow near-maximal effort throughout. The warning beep at 10 seconds remaining signals you to finish the current movement and note your score. Common AMRAP workouts include Cindy (5 pull-ups, 10 push-ups, 15 squats, 20 minutes).
Ten minutes balances sufficient work volume to produce cardiovascular adaptation with a duration short enough to maintain intensity. Longer AMRAPs (15-20 min) shift toward aerobic endurance; shorter AMRAPs (5-7 min) are more anaerobic in character. Adjust based on your training goal.
