VIEWING: You are currently looking at our Red - 15 to 35 Pounds 1/2 " *4.5mm - These bands can be used in stretching, jumping and other light exercises. This level band is great for providing a small amount of support for pull-ups. PRODUCT RANGE: Here are the details of all the other bands we offer: Red - 15 to 35 Pounds (1/2 " *4.5mm), Black - 25 to 65 Pounds (13/16 " *4.5mm), Purple - 35 to 85 Pounds (1.25 " *4.5mm) SUGGESTIONS: Customers generally buy more than one band and combine the bands for more efficient training. Combining bands gives you 3 levels of assistance - one with the thicker band, one with the thinner band, and one with both bands. This allows you to do sets where you start with the thicker band and then add the thinner band to squeeze out a few additional reps. As your strength gradually increases, you can switch from double bands to the thicker band and then the thinner band alone. GUARANTEE: Whether you are just starting out with pull ups or you are an athlete working on regaining or enhancing your strength, Hawk resistance bands will help you take your training to the next level. Try it for 60 days. If during this time you don't like or feel the benefit of the bands, send it back and we will give you a refund.
