Input:
This product is decent. The stack-able bands gives you a great variety of resistances. You can do a full body workout at home. The bands really give a killer workout. The piece that allows you to attach the bands to a door works great. This piece is best for back exercises especially if you do not have a pull up bar. This set is definitely worth it for the price. The one downside is that I can see myself peaking out with these bands. May have to get bands with more resistance down the road. But other than that these bands work well.
