The GHD back extension Iso Hold is a variation of the GHD back extension and an exercise used to strengthen the muscles of the glutes, hamstrings, and lower back.
The emphasis of this exercise should be placed on your glutes – as over emphasizing movement with the lower back can result in spinal injuries.
The angle the GHD provides to this back extension provides a greater challenge for you to progress to after mastering the basic hyperextension.
With the added iso-hold in this exercise, you focus on building the muscle with isometric tension, a powerful tool and form of progression.
