I don't do anything like that but SS trains and competes in BJJ. She won Masters Worlds Gi and No Gi this year as a purple belt. Also took Silver at adult Pan's this year to. Her conditioning is sick from rolling 4-5x week and whats crazy is her strength is still through the roof.
Heavy bag twice/week....broke a couple bones in both hands from fighting over the years (some sanctioned, mostly not) and I have to be very careful with wrapping....I'm jealous of those that can just throw on some gloves and go at it.
