Buy 2 speed belts and a pair of 10-foot SLEEVED bands and train together.  These bands only stretch 12 yards and then the sleeve stops.   The sleeve is a safety feature that keeps the bands under a controlled stretching point and if they were to break, the band stays in the sleeve.   Choose your color of bands based on your age and strength.  

8–11-year-olds - GRAY

12–15-year-old - RED

16 and up - BLACK

SAFETY MESSAGE:

- make sure belt “clicks” and locks before using.

- Training video and spreadsheet included. 
-Connect 2 10-foot bands together to form a 20-foot band.  20-foot bands safely stretch 25 yards.
