Spatts: If I come up there...can I see you tangled up in the chains??? As big as my belly is...it might take a pair of the heavy bands to go around my belly...or to keep my tounge from the floor...
While GM's WILL work your hamstrings (not even secondarily, but still), I'm not sure they are the most effective way to work them. Either your hammies or lower back will suffer...hard to work BOTH effectively with GM's, due to range of motion and the volume often associated with form issues.
anybody know a site with a description and/or video of how to correctly do lifts like GM's and squats, bench and deads? i went to exrx but the videos looked painfully awful in technique..
as a beginner, and probably even throughout the entire time i lift...i will probably always need to work on form and perfecting my technique
