Here's a Week's Worth of Belly-Fat-Busting Workouts
Doing HIIT every single day isn't recommended (your muscles need some R&R so they can properly rebuild, and doing intense exercise every day can increase your risk of overuse injuries), so Miller suggests capping your HIIT sessions at four per week, plus two steady-state cardio sessions and a rest day.
Here's your schedule:
Monday/Day 1: Workout 1
Tuesday/Day 2: Workout 2
Wednesday/Day 3: 20- to 30-minute jog, or speed-walk
Thursday/Day 4: Workout 3
Friday/Day 5: Workout 5
Saturday/Day 6: 20- to 30-minute jog, or speed-walk
Sunday/Day 7: Rest!
For the Workouts
Do each exercise for 20 to 30 seconds, rest for 10 seconds then move on to the next exercise. (When you're doing a single-leg, or single-side, move, do 20 to 30 seconds on each side before moving on to the next exercise.) Repeat the entire circuit two times. You can bump up the intensity by moving faster, while still maintaining good form, of course.
