I settled into my two times per week routine. For the core workout, I'm doing the following:
Pull-ups 10,9,8 Dips 3x8
L-sit 40 sec one-leg x 2 Squats 2 x 8 (35 lbs)
Push-ups 3 x 10 rings Low-rows 3 x 9
I'm still doing the warm-up, stretches, core work and position holds (handstands, etc) although I've shortened it a bit. The overall workout takes less than 45 minutes usually.
Twice a week has been great for me. It allows me to run at least once a week and do BJJ three times a week. It's been a great balance and I feel stronger than I've been in the last 25 years. I'm also working out almost as much as I was when I was trying do RR three times per week. Sometimes less is more :-)
