RingBell Interval

Three minutes on, one minute off. The oldest interval in the sport, and the easiest to lose track of once your heart rate climbs.

RingBell Interval calls the rounds so you can keep your hands up.

THE TIMER
• Big, readable digits from across the gym
• An audible bell at the start and end of every round
• Warning tone before the round closes
• Rounds, work time and rest time, all yours to set

BUILD THE WORKOUT
Twelve threes with a minute rest, or thirty-second bursts with fifteen seconds down — whatever the session calls for, save it and it is one tap next time.

AFTER THE BELL
Every session goes into a history, so a month of training is a list rather than a feeling.
