Well your starting at really high reps. You'd be better off starting at around 7 or 8 and adding reps then maybe sets. That'll let you build your endurance while progressing better. Plus you'll be going heavier to strat with. Also this way you won't be going as high as 15 reps on stuff which is not going to work well. Going that high gets counter productive as far as progression. Meaning when you go to add weight you won't be able to add as much as you would have if you had start at say 3 sets of 7 and went to 3 sets of 12 or so (or another set which would not really be necessary).

It's perfectly ok if the rep ranges meet in the middle on the heavy and high rep days. I have a feeling you were trying to avoid that but it's really not necessary. On the heavier days you could start as low as 5 reps on the secondary stuff and if you were to go up to around 7 reps it's good. Really it's the starting intensity and progression that separates them and not some arbitrary definition of what the reps should be. Obviously the heavy days would stay on the lower to moderate reps side and the lighter days can go from the moderate to high reps side. Hope this makes sense.

Try to set yourself us on GHR's so that you start with a slight bend at the knees. You don't want to start with your knees extremely stretched out. I had a lot of discomfort at first too but after a little while I was good to go. Be careful. And again, leg curls are NOT the same. You need things that immitate the function more and leg curls only fulfill one function...knee flexion.

P.S. Phil, don't sweat one little side trip in his journal. He's used to bb circus where you get 5 or 6 pages of hyjacking on a regular basis
