Good to see healthy efforts here folks
the mainstream media seems to get "healthy" wrong. If you want to be fit and active for a long time you need a mix of weight training and cardio. Don't go overboard on the high impact cardio. Cycling and rowing machines hurt your body a lot less than running and still have strong heart/CV beneficial effects.
I've found prowler pushing to be an amazing exercise as I don't have enough patience for long drawn out cardio

Take a multivit/mineral, get lots of fish oil, enough vitamin d [5000iu] per day seems to be good and get your free testosterone checked out
