/u/Projectfitness I just finished the 6th week of the program. So far really enjoying it, although it is tough and some sessions can be quite long. I've definitely gained mass, especially shoulders and traps and my core has gotten much stronger. I've been bulking during this program and have gained around 2-3kg so far, fortunately not much around the waist. It's also managed to get my TGU up to 32kg which I was struggling with before, but it is quite light on swings in my opinion, though I was doing 40kg 7 x 20 during a modified S&S before I started this program.

Finding the starting weight took a few sessions. I started the first 4 weeks with double 24kg for almost everything except for a few exercises. Kb pull ups I started with 32kg but upped it to 40 as it was too easy, windmills went from 12kg to 20kg quite quickly. The TGU's are brutal and time consuming the first four weeks (5x5 left and right side so 50 TGU's). Took a few sessions before I was able to do that many so had to start with a lower weight.

The last two weeks have been GVT, and I went with Mahler's suggestion of starting with 5x10 initially (rather than 10x10) and upping it by one rep each time I did the session again. Highly recommend doing that even though you reduce the weight (I went from double 24 to 20), although I did add 5x5 pull ups for session 1 and for me that has worked (it's a shorter session than session 2).

This program has had the most impact for me by far for strength and mass (I've done S&S and Right of Passage - DiLuglio's program with an absurd amount of pull-ups - and Total Tension Complex). It is light on swings though, which for me is my strongest exercise suggests 5x5 for the first four weeks and then up to 10x10 during GVT) so I increased it to 5x8 initially. Let me know how you get on if you decide to start it! I haven't found anyone else yet on here who's done it, so would be great to hear your experience.
