Glute Ham Raise
The gluteham raise, in relation to the hyperextension is different because the range of motion of this exercise carries you beyond parallel, allowing a full hamstring and gastroc contraction, which is particularly useful for a strong punch, sprint, etc. A hyperextension is mainly for the lower back, whereas the gluteham raise ties the lower back into the hamstrings.
1. Begin by getting on a glute machine and lowering your upper body from the waist so your head and upper body are hanging down.
2. Raise your body as high as you can then, lower back to starting position. You have completed one repetition. The glute ham raise is moderately difficult and should be executed in a smooth, fluid motion. Care should be taken to avoid jerking motions and rapid speed.
