Also a few points of “ trust me advice “
Stretching is vital - so are leg days - to live an active life as we age .
Some of the best mtb’ers I’ve ridden with are 60+ - blow 25 year olds away .
People stopped moving during the pandemic - never mind working out .
I agree with legs and strength training in general being vital. I’m 8-9 inches shorter than you and only 35lbs lighter, but I don’t have a gut. I do have 100lb quads though
Hard 75 would be a good routine for a lot of our guys. The versions I’ve seen of hard 75 are harder… too stringent for me, but I like the one you posted. The ones I saw all had like no alcohol or sugar for 75 days, etc. As a dad and husband going on 36… I’m not going 75 days without a drink here or there haha like you said, IPAs and sugar.
