4. Click "Start" and follow the audio cues

Sample Workouts

• Tabata: 20s work, 10s rest, 8 rounds (4 minutes)
• HIIT: 30s work, 15s rest, 10 rounds
• Circuit: 45s work, 15s rest, 6 rounds

Benefits of Interval Training

HIIT burns more calories in less time than steady-state cardio, improves cardiovascular fitness, boosts metabolism for hours after exercise, and helps preserve muscle mass while losing fat.
