over the past few months I've notices that my knees are aching. I don't spring out of my seat like I used to, and I'm terrified that it's only going to get worse.
I used to do a lot of heavy weightlifting, so I think it may be a part of the problem. I'm a tad overweight. At 6'2 I'm 250 lbs. I know that sounds like a lot, but I'm really wide and thick, and at 200 lbs i'm pretty much skin and bones.
Apart from getting my weight down, what can I do to preserve my knees for the long haul??
