If you enjoy doing glute/ham raises, but don't want to spend a ton of money, this strap is perfect for you. The Glute/Ham Strap is an inexpensive, equally effective alternative to a full GHR rig.
The strap can attach to any bench or study pad, turning any equipment you already own into a glute/ham raise setup, and is highly effective at targeting both your hamstrings and glutes without putting any stress on your spine. This allows the lifter to build your posterior chain, while minimizing injury risk.
