3. Standing alternate knee to elbow crunch


Stand with your feet at a comfortable width with your hands raised to touch your ears.

Initiate the exercise by raising your left leg and slowly flexing your trunk and rotating your upper body so your right elbow approaches your raised left knee. Your knee and elbow do not have to make contact. The key to the exercise is to maintain a tall posture and avoid rounding the low back. Repeat the sequence on the opposite side.

Perform 12 to 20 total repetitions.

Trainer Tip - be sure to raise your knee towards your elbow. Do not sag at the waist or pull down on your head with your hands in order for your knee to meet your elbow.
