Hey Jim, had a couple questions about 3's Pro, specifically as regarding the deadlift.
I am just coming back from a pretty bad disc herniation at L4-L5 that had me sidelined for the better part of a year. After I swallowed my pride and admitted I was hurt and couldn't fix it myself, I eventually found a great physio, followed all his directions, and have been given the go ahead to start training again. I bought your books and have been doing 5/3/1 for 6 weeks now. Prior to that I was doing the GSLP from StrengthVillain and my PR deadlift was 585x1 and 535x5, pulling conventional.
So far I have been easing myself back into deadlifting. I've switched to sumo. No sets higher than 5. Really conscious about form at all times and taking it slow. I pulled 405x3 last week from the floor, and rack pulled conventional 485x3 the week before. So I'm moving forward, slowly.
As I program deadlifting back in so its more regular, I'm interested in 3's Pro. So far, on the other lifts, I've been doing BBB. For deadlifts I'm doing back raises and hanging knee raises as assistance instead of the 5x10 sets, though I do like your 5x3 @ 75% sets from the Beyond 5/3/1 program you posted here. Might try those out.
The biggest question about 3's Pro is, for the first week, the one that is usally 5's, do you alter the percentages at all? Match the 3's week? Or leave as is at 65/75/85?
Normally I bet you compensate for the lower percentages by killing your last set even harder, but I want to keep the reps/set down so I think I'm going to cap my 3+ sets at 5 or 6 reps. Maybe do more Jokers to compensate?
Anyone else coming back from disc herniations, would love to hear what works/doesnt work for you.
