Glute Hamstring Developers
The Glute Ham Developer is a staple item of any Crossfit gym for it's use for GHD sit-ups, hip-extensions, and wall ball throws. An athlete that possesses the necessary strength may be able to perform a full glute-ham raise. A glute-ham raise is a GHD hip extension, followed by a GHD leg curl performed together, as one continuous movement. This more completely trains the back extensors and hamstrings as an integrated unit.
