Hey all, I've been doing BGB for the past several weeks and I feel pretty fatigued after the first three days, but on this day I'm not feeling it so much.
I'm doing the following for legs:

Romanian DL 5x5
Good Mornings 3x8
Leg Extensions 3x12

Now, the leg extensions are hitting my quads good, but I feel the RDL in my back a lot more then I do in my hammies. And I don't feel much of anything from the GM's.

Now I've checked both

And my form doesn't seem to be the problem...

Any tips for either exercise?
