Feel Strong and Sexy This Summer With Halle Berry's Equipment-Free, Ab-Shredding Workout

Start by holding the towel at both ends with your arms fully extended as you perform a sit-up. Complete 10 to 20 reps.

Start by sitting on the ground. Your feet can be lifted up off the ground or placed on the ground for more support (here's a few Russian twist variations to try). Hold the towel in both hands with your arms fully extended, and slowly begin to twist toward your right. Return to the centre, and then slowly twist toward your left. Complete 10 to 20 reps.

With the towel in your hands, perform a squat, and then stand all the way up as you press the towel overhead. Finish off by jumping over the towel (as if you were jumping rope) followed by a burpee. Complete 16 to 20 reps.

Start standing with a towel in both hands and your arm fully extended overhead. With control, perform a reverse lunge by stepping your right leg behind you. Using your core, stand back up and drive your knee up to the side. Repeat with the left leg. Complete 10 to 20 reps.

Start standing with the towel on the ground about a foot away from your right leg. The towel should be used as a marker to jump over as you perform skaters. Complete 10 to 20 reps.
