Ann Arnoult explains why making Pilates exercises with exercise bands is good for your body. It adds resistance, that increases your flexibility and motion. You can work your al body using it. There are demonstrations of exercises, using the band. For working your legs and back, lie down, put the band on your feet and start exercising, by bending the knees. The seconds exercise is by sitting on the floor, straightening your legs. The third exercise: you have to kneel on the floor, put the band under your knees, and start pulling it up with your hands. This exercise will help working you triceps.
