How to Use a 30 Second Repeating Timer for Training

Whether you are working through kettlebell swings, sprint intervals, core circuits, or fast-paced bodyweight exercises, a repeating 30 second timer helps you keep your intensity consistent without the need to watch the clock.
You can use a 30 second timer for fitness challenges, combat sports drills, CrossFit style workouts, or as part of your personal training sessions. It is also perfect for managing high-output cardio efforts or recovery intervals between heavier lifts.
