Volume

[Altamir]

I'll add a little bit as to your concerns about "lose some insulin sensitivity/ gain fat a bit too fast." You will not find a more metabolically challenging body building based program out there than FT. A very large majority of people I know, including myself, when they first switched to the program (without adjusting calories), either went from a bulk to a recomp, or had to add additional calories to keep weight on. Nick has got it spot on. Just jump into it, trust the process, and I would also REALLY advise against starting out at tier 3. You're already in a mind set that you need more volume, but tier 3 is not only a meat grinder, but also a bit confusing to some folks first running the program. Stick with the basics, get your feet planted in the program, and go from there. You MAY end up at tier 3 and come back to this thread and call me a wuss but I can almost promise you'll have been better off starting at a lower tier and working your way up.
