Start your fist multi-tasking ab move on the floor, for this chest fly exercise with an inner thigh crunch you will need 5 lbs. With the hand weights, do an open-close crunch 20/30 reps.
Next, move into a side plank and lift and lower a flexed foot. Be sure to do both sides!
For the last engaged ab move, bring the upper back into the mix with a middle plank on your hand weight and lift and lower the arms.
You can always multi-task by throwing in the opposite arm and opposite leg. After those moves we can already hear the beach calling, are you ready for your bikini this season?
