3. HIIT Workout
Interval training (HIIT) uses high-intensity exercises combined with short rest periods to maximize calorie burn and cardiorespiratory fitness.
A HIIT circuit for both beginners and advanced
for beginners: start with 30 seconds of workout, followed by 30 seconds of rest
more advanced: do 45 seconds of work and 15 seconds of rest
2 to 3 days a week is a solid amount of HIIT, combined with 24 hours of rest and recovery between sessions.
