We have a lot in common... Aside from the common first/last name, I'm 43, do BJJ (started about 2 months ago). Did foundations for several months in 2014 (maybe it was '15), and am just now coming back to it. Mostly because I realize I need the help with mobility.
I look forward to watching your progress and comparing notes. Hope you recover well from your injuries.
Completed 1st workout after update, lower and upper body trained in 28 mins. It felt hard to keep up at times. It felt like a race !! I think I will practice small sets offline to work out correct form.
