I know the struggle as someone between the ages of 27 and 63, and also around 200 pounds. But, skating is like, the best thing I have in life, and I fight like hell to be able to do it. I didn't skate much for a year in there, injured, and I know first hand that if you don't use it you loose it.
This is not for everyone, but for me, I follow a anti-inflamatory diet. I was clued onto a book called the virgin diet which works out well for me. I basically just don't eat the 7 foods that are no-no's on the diet all the time. What that means is that I have to cook every day, and that takes time. But again, I fight like hell, and when you aren't inflamed, you feel better.
Also, I do a youtube 15 minute ab workout three times a week, and walk several miles a day. I work out on an elliptical during the winters, but hey, it's time to skate now, and once you are at a decent cardiovascular level I'd rather focus on the abs and just walk to save my legs for skating. Also, yin yoga on days when I'm a total pile. That shit rules, and it's basically efforless.
