Difficulty: Moderately Easy
Things You’ll Need:
Reverse Twists With Chair
Step1
Find a sturdy, heavy chair, bench or other piece of furniture with a leg that can be grasped and that will provide resistance during the exercise instead of sliding across the floor.
Step2
Position the chair behind your exercise mat with a leg in the center of the mat's width.
Step3
Lie down with your back on the mat. Turn your lower body towards one side of the mat and put one leg on top of the other. Bend your knees at a 90-degree angle.
Step4
Raise your arms above your head and interlock both hands with a grip around the chair leg.
Step5
Do the reverse twist by lifting your legs, still held together and bent at the knees, and pointing your feet at an angle away from your body. Remember to keep your shoulders on the floor.
Step6
Bring your legs back to rest on the floor by turning your hips and legs to point to the opposite bottom corner of the mat.
Step7
Do a reverse twist on this side of the body. Continue with as many repetitions of the exercise as you can manage.
Reverse Twists Without Chair
Step1
Lie flat on your back on the exercise mat. Extend your arms out in a straight line from your body. Turn your hands away from your arms in a 90-degree angle to better anchor your arms on the floor.
Step2
Lift your legs together above the floor so that they form a 90-degree angle to the body.
Step3
Lower your legs, keeping them tightly together, to the right at the halfway point between your original position and the floor.
Step4
Return your legs in a controlled motion back to the original leg position.
Step5
Lower your legs to the left to the halfway point. Return your legs to the original position. Do 10 more repetitions.
