Hi bigwinsta. What’s up, mate? I’m on week 4 of that program, and liking it very much. I’d suggest you do it for 12 weeks, not the 9 weeks that’s on the spreadsheet (just extend the sheet 3 more weeks).
I had the same problem regarding RHs. My solution is like Minotaur’s, only I angle the bench back at 45 degrees. Getting on is amusing, and I get plenty of stares when I do this exercise from the other patrons, but who cares?
I haven’t quite solved the weight issue. If you put a dumbell between your legs, it will tend to roll if you bring your legs above parallel. I’ve tried attaching myself to a low cable pulley, but it didn’t work very well. I’m thinking of just using a regular belt (not a lifting belt) to tie the dumbell to my feet so it won’t roll.
At the moment I’m just doing 20-25 reps without any weight and holding the top position for a few seconds. I had never done this exercise before, and my lower back and glutes get quite a beating from it.
If you want to discuss/comment this workout, feel free to PM me. It’s my first time on it, so maybe we can share some info/tips.
