Use it to replace: A resistance band

How: Combine a resistance exercise that works the arms with a lower body move to kill two birds with one stone

Try: V Squats
Start by standing with feet a little wider than hip width apart. Grip the ends of the towel with each hand and hold it taut overhead, pulling for resistance. Lower down into a squat, bringing the towel down in front of your chest until it is parallel to the floor, then squeeze your glutes and return to standing, raising the towel overhead again. Complete three sets of 10.

Use it to replace: Captain's Chair Machine

How: Instead of curling up on the couch, sit upright to target your lower abs

Try: Couch Criss Crosses
Sit on the very edge of your couch and brace your core to maintain a straight, upright posture. Straighten your legs out in front of you and point your toes. Use your abs to cross your legs back and forth in a scissor motion for 60 seconds.
