Designed For Simplicity

Every resistance band exercise in the TA2 Build program is demonstrated on screen with proper technique. You’ll know exactly what to do on every set.

Ultimate Convenience

With TA2 Build, you not only get results fast, but you have the freedom to train anywhere, anytime – at home or even on the road. Your bands and your phone are all you need!
