As if normal pull-ups weren't hard enough yet... ;). Take your pull-up to the next level by giving yourself an extra challenge with the Power Rollers. 

Because of their thick, spinning handles this is an awesome way to get some killer forearm flexors, while also training your pull-ups. 

You can chose to grip it with your thumb over the handle (a great way if you want to train your cup for arm wrestling) or under the handle (making it more of a grip exercise).

Specifications:

• Bundle includes 2 Power Rollers, 2 carabiners, 2 straps
