Just curious, but does this have benefits over performing a GHR? Or is this an exercise you could possibly use as progress towards a GHR?
People keep saying how hard GHRs are, but I manage to whack out sets with a 15kg plate clutched in my arms and a BW of 100kg...
Is that normal, or is it likely I am doing something wrong?
Probably, hard to say though, video would be the easiest way to tell. Are you also making sure you keep your hips forward and in line with the shoulders? Lots of people tend to have their hips shoot back when they get tired to make the movement easier.
They stay in line for the most part, unless I'm really fatgiued on the last reps of the last set.
I'm mainly concerned about how far back I'm placing the foot support, and the subsequent quad positioning on the pad. There are two settings that are plausible where either I have the pad right above my knee (which feels more than uncomfortable), or it goes to about 1/3 up my quad (from the knee). I use the latter.
