My husband was a competitive soccer player his entire life. Unfortunately, his knees have gotten really bad, and he's had MRIs and physical therapy and all that, but nothing has helped. As a result, he physically cannot play any more. He's not heavy or anything, but he's lost a lot of tone and I know he doesn't feel as good about his body.
Is there anything that could replace it that wouldn't put a lot of pressure on his knees? He doesn't really enjoy cycling, and weight-lifting seems more like maintenance work than fun to him. Mark Sisson is always talking about incorporating play into your workouts, and it's like my husband can't do that at all, which really sucks.
I feel like I'm looking for a magic bullet (something fun, competitive, physically strenuous, and yet doesn't stress the knees!), but I thought someone out there might know of something that I hadn't thought of.
