My normal schedule:
M - 7:00 AM grappling, then two Muay Thai sessions at night from 5:00 - 7:00 PM
T - 6:30 AM grappling, 12:15 PM open mat
W - Lifting in the AM, 11:30 AM Muay Thai
Th - Either 6:00 PM MT sparring, or 5:45 PM grappling and 7:30 PM MT/MMA sparring
F - Lifting or bagwork in the morning, 11:15 AM grappling open mat
Sat - Lifting if I skipped it on Friday, or nothing
Sun - Rest
So somewhere between 8-10 skill sessions with some S&C thrown in. I'm mostly just lucky, because I have a very flexible job where I basically make my own hours and I have very reliable childcare. I'm also willing to get up really early and put work in, whether that's making 6:30 AM practices or just getting up early to literally work so that I can train later in the day. I also won't maintain this schedule much longer, 2018 is probably my last year of serious competition as I'm getting old and when I stop competing I'll scale this back significantly. Or maybe I won't, I'm more than a little obsessive, but that's the plan at least.
