Thanks everyone.
Good luck with the leg curl machines, most of them I have seen will not work because they use a solid pad that runs along your whole body. The one at my gym looks like this:

Now that I look at it, I wasn't backwards, just shifted forward.
Just be careful of those handles.
The 1-leg curls were not exactly easy. I was having a hard time keeping my body straight, and it become more of a balance issue than leg strength. The GHR's are really a challenge. Sorry to disappoint you, but I said that I
can't do them without help from my arms, but i'm working on it.
Tony, I promise, no more fat loss routines any time soon. I'm planning on starting NROL Strength I next.
