## What is 20 Second Exercise?

20 Seconds is an Apple Watch timer designed for slow, controlled strength-training repetitions.

Each repetition lasts 20 seconds. Strong haptic cues help you stay on pace without repeatedly looking at your Watch. A repeating pattern of one, two, or three haptic alerts identifies the beginning of each repetition, and four alerts mark the halfway point.

The app can display your live heart rate during an active workout. Pressing Stop ends the timer, workout session, and continuous heart-rate collection.
