These resistance bands add that extra bit of resistance to your workout that not only forces your body to perform better but ultimately provides lasting results. These bands are perfect for athletes learning pull ups, chin ups, ring dips and muscle ups. They are ideal to develop muscle memory and get you to do those kipping pull ups and strict pull ups in no time. They can also be used for a challenging power-lifting session. These bands are made of quality material. Continuous layers of tough rubber add a level of resilience and sturdiness that makes these bands outlast any rival. They won’t break on excess stress and won’t be easily deformed. There are 5 bands, each with different resistance and power levels. Please select the band that best fits your fitness level and needs. The thicker the band, the most assistance it gives for pull ups, chins ups, bar muscle ups and ring dips. As your skills improve, you can go to less and less resistance. If used for power lifting, the lighter bands are perfect for triceps and biceps exercises, while the thicker bands are helpful for squats, deadlifts and lower body exercises. Each purchase is for a single band. Each band is 41″ long. They are great for traveling and are easy to transport.
