my opinion based on my experience is "yes there are benefits to moving to a 32 kg bel for TGUs when you are ready". Besides the strength, I have noticed solid muscle growth in the shoulders, upper back, traps, triceps and forearms.
I had the same question when I first started on SS in May and with a 35 lb DB. I was even considering getting an in-between sized 44 lb bell in anticipation of moving up in weight but thinking the 24 kg would be out of reach for a while. Now I am able to use a 36 KG bell that I cycle in for some SS reps - like 1-3 with 36, 4-5 with 32 and can confidently use the 32 (and meet the SS standard for the TGU portion, not swings yet). My experience has been
- Patiently keep using the weight you feel confident in and build up the volume
- when the current weight feel "easy" for your body, try a rep at the next weight up.
- slowly add a rep or 2 with the heavier weight until you get to all 5
For ex, when trying 32 for the first time, I did it on my second rep and just to the standing position.
I was sort of shocked and really excited that I could actually do a half rep!
Now I am able to use a 36 kb bell for all reps if I chose, but still cycle those in for 1-3 per SS session while I continue to use the 32 that I feel that I "own".
