That's the way I saw it too, but I'm making great progress! I've never tried high frequency with these big compound lifts yet, but it's definitely working for me. Besides the knees..I was apprehensive to switch to this 5x5, because it's 3 compound lifts per day, 3 days a week. I know the 5x5 is a well proven program so I said fuck it, I can do anything for 8 weeks right? I'm mostly focused on adding reps to my squat now, if I throw the Deca in and wrap the knees while adding weight on, it might really backfire on the tendons..my bench is getting added reps where I was stalled too. My rows and deads were way higher, but you add them at the end here, so in a few weeks they'll catch up. Hitting them last while you're gassed is hard, but they go up each workout! So that's good progress in my book. Saftey first though..
Edit: I have bitch legs, so I'm prioritizing them. That impacted my decision to use 5x5.
