7 Minute Ab HIIT Workout
HIIT helps you blast more belly fat, save time, and burn way more calories (even after your workout is long over) than a lower-intensity workout alone.
The ACSM's interval workout consists of 12 exercises, which should be done at an intensity of eight on a scale of 10; each exercise lasts 30 seconds, with a 10-second rest in between. Repeat the circuit if you'd like a longer workout.
Keeping the intensity up and the rest periods short!
