TB12™ Shoulder Performance Kit contains the same resistance bands that Tom Brady uses at the TB12 Performance Center. The kit includes pairs of bands in 4 resistance levels and a portable anchor spine that attaches to a standard door to enable workouts anywhere. These bands have ergonomic handles and are made with surgical-grade dipped latex tubing sheathed in ballistic nylon for maximum safety. Unlike weights, bands provide progressive resistance throughout the entire range of motion while adjusting to each user’s natural strength curve. The kit also includes a booklet with 12 TB12-aligned exercises.
