OK, I'll get in on the bandwagon here (a month late). I picked up Big 6 & Strong with Geoff's sale, and I had a friend (Thanks Bob!!) gift me KBM, as I'm looking to put on some muscle this year. I'm starting my third week of KBM, and it's simply amazing. You are pushed hard thru the progression and compared to the other 12-week program of Geoff's that was posted, it's very similar. I think KBM has some nuances that really make it stand out though. I've been pushing thru S&S previously, as well as another 2-day leg program (Kiwi program in 4-hour body), and I thought that was brutal.
I. Was. Wrong.
I was doing complexes with front squat reps around 10 (weight was supposed to be 13 rep max), and went up from a pair or 16's to an unever 16 & 24. Here I figured I was pretty strong when it came to front squats, as I was doing 8-10 reps, and they felt good. Apparently, none of that pre-training prepared me for KBM though!! The 16's are kicking my butt with these complexes, and even the front squats with 8kg less, I feel like I haven't been squatting at all!! If anything, the Kiwi program's saving grace for me is I'm recovering easily enough to get to the next day.
I'm going in for my body composition(DEXA) next Friday (end of week 4), and I'm tempted to schedule another one at the end of the 12 weeks depending on where my muscle mass is from the initial I had from Sept 2017. It'll be curious to see what my changes are, especially being on a keto diet. I'm also planning on doing STRONG & ONE combined after the obligatory week off at the end of the 12 weeks (lots of walking planned). Its all planned in a pretty spreadsheet that's probably not infringing on any copyright...
