Building a simple interval workout
Interval training alternates short periods of hard effort with rest. The four presets are common formats: Tabata 20/10 × 8, HIIT 40/20 × 10, 30/30 × 10 and EMOM 60 × 10 (every minute on the minute, no rest). 30/30 × 10 is the only one with as much rest as work. Under Sets, warm-up & cool-down you can add Warm-up (seconds) and Cool-down (seconds), so the whole session runs from one Start.
Tip: Write your exercise list down before you start and do them in order, one per round. The beeps tell you when to change, so you never need to look.
