These are nice bands but you do have to "install" them to get the widest range of motion out of them. If you don't precisely center them so there's an equal length on both sides, the short side will stretch the fabric too far and "bottom out". However, if you precisely center it, both sides have good range of motion. I installed mine with strap around a lolly column in my basement and used a zip tie to secure the bands to the strap. This keeps it centered and works really well. Band broke (separated from handle after 3 month's use, so downgraded my review by one star. I had some difficulty reaching the company but turns out their office is closed this week for the holiday. Looks like they'll be sending me a replacement. 1/1 Update: replacement received and all is fine again. Kudos to Worldwide Fitness for standing behind their product!
