product description 1. Exercise bands are the most versatile exercise tool for dynamic exercise. Originally designed to help with pull-ups, they are now used to assist pull-ups, including belts, weights, calisthenics, stretching, and agility belts to create progressive resistance that matches the intensity of the exercise. 2. Buy multiple bands and combine bands for the most efficient training and faster results. Combination bands give you different levels of assistance that will allow you to progress faster and work out in different rep ranges. You can also alternate bands for groups, starting with thicker bands and adding thinner bands to squeeze out more reps when you fail. This is the best and fastest way to make progress in any sport. 3. Our resistance bands are designed for every level of conditioning, from beginners to professional athletes. These exercise bands will help you take your training to the next level. 4. Ideal for beginners, intermediate and advanced users, designed to suit individual fitness levels and workout routines.
