I made the same mistake when I first read it. Read carefully, he says he can't clean or swing
double 48s. Swinging a single Beast isn't a problem for him.
Just never tried more or is it truly the heaviest you can snatch?
I'm asking because the heaviest I ever snatched was 36, but I think I would be able to snatch 40 for 2-3 reps. I just don't want to try, because I don't feel too confident about the 40.
The TGU is way too light. Not that it's unhealthy or anything, but if you really can't get up with more than 32 while at the same time being able to support a lot more weight during ballistics (44-48 Jerk, ~38 Snatch) hints at imbalances or weak points somewhere.
Usually the TGU is the strongest or very close to the strongest lift and even though you practice the Jerk a lot, the discrepancy between your Jerk and TGU shouldn't be that big. Also the snatch and press to TGU ratio is off - a support like the TGU should always be stronger than an "active movement" like the press or snatch.
You learn to control and stabilize a weight through the TGU and groove your hip hinge through the swing first. Then you add arm-movement to it with the press. Only after you mastered (overhead-) stabilization, arm-movement and the hip hinge you combine all of those three and start to work on snatches***.
In other words "don't put something overhead with speed and momentum that you can't get there slowly and under control". That's how it's done in the SFG and RKC.
That way your TGU should naturally be stronger than your press and snatch. Snatch and press are about the same.
No offense, just pointing out something you or others with similar ratios might want to address in your training
***see Enter the Kettlebell. You start with TGUs and swings in the PM. Then it's C&P and swings during the RoP and only a small portion (the light day) is reserved for practicing the snatch.
For me:
TGU - 48
Jerk - 48
PP - 44-48 (never really tested)
Press - 40
Snatch - 36 (probably 40)
Clean - 48
These are all truly heavy for me. Subtract 4Kg off of each to get the weights I feel 100% confident with.
