band standing crunch

Attach the band to a sturdy anchor point at waist height. Stand facing away from the anchor point with your feet shoulder-width apart. Hold the band with both hands and bring it up to your chest, keeping your elbows bent and close to your body. Engage your abs and slowly crunch forward, bringing your chest towards your knees. Pause for a moment at the top of the crunch, then slowly return to the starting position. Repeat for the desired number of repetitions.
