This 5 min intense ab Workout challenge is AMRAP (as many rounds as possible) style and it totally burns out your complete core muscles, upper abs, lower abs, obliques, & lower back.
There are total 4 exercises in each round and the challenge is to complete as many rounds as you can to maximally burn out your ab muscles:
Exercise 1: 10 reps lying down leg raises, targets the lower abs
advanced version: 10 reps hanging leg raises
Exercise 2: 5 reps wood choppers on each side, targets the obliques
use water bottles or body weight if no access to weights
Exercise 3: 5 reps 1 inch worm + 5 plank jacks, targets the upper abs
Exercise 4: 5 reps high plank to upward facing dog, targets the lower back
Hopefully you find this fun ab workout challenge intense and effective. At the end of the workout I was really tired and abs were on fire.
