It would be great if the seller can provide a workout sheet.I use the green band tied to my treadmill for chest pulls. It works great as you can pull it and extend your arm across your chest for a maximum workout.

They are thick, hefty, high-quality latex, and the range of resistance is ample. At 41 inches, they are just long enough for our next-door neighbor's son to use them to support his pull-ups, but short enough for use in squats and curls. An excellent product.These are a set of 4 resistance bands.

Good set of bands, would recommendThese bands are strong and provide users the ability to build strength as heavier bands are used. The first and lightest band is thinner than the other three, with each one adding progressively more resistance. The bands are each thick enough to allow a good grasp with your hand. The resistance can be varied on any one of the bands simply by grasping them in different areas. The shorter the span you are working with, the greater the resistance.The bands are complete circles; that is, they are not cut, so do not need to be tied together to work with them.
