Flytool Pull Up Assistance Bands Adjustable Elastic Chin Up Assist Resistance Bands Full Body Workout Programs High-Performance Pull up & Chin up Assist Bands

ITs hard to take out the elastics to get a different force and even harder to put back in. Not that that's the reason i'm giving a 3. It does it's job, nothing more nothing less, that makes it average, not great.

This product affected my workouts in a positive way. I'm telling you right now, if you're on the fence about buying this thing, don't hesitate. I worked harder on my pull-ups than ever before, and I knew I wasn't cheating.I finally working my back properly while doing pull-ups. This allows one person to complete the pull-up alone over time. This will definitely be a game changer for your program, be it p90x, or your own regimen.

The best part is that you can choose your own strength. The 3 elastic ropes can be loaded and unloaded at will to adjust the strength. Great design!

Works great and has helped me build strength to do pull-ups .I can now adjust my resistance and much more easily do pullups. Which is helpful when trying to build up my strength. Overall, I very highly recommend this product. I wish I'd bought it from the start. Hopefully I'll remember to come back and update after more progress!
