I've always worked out at home. This is as much due to not liking 'chrome and fern' gyms as anything. I also live out in the sticks, and the constant travel becomes a drag - an hour long workout can become 2 hours and more with the travel time, and that's a bind. Not to mention expensive - fuel is damn expensive here!
I've also been considering returning to judo - I did a year or two of it about a decade ago, then redundancy and a new job with different hours forced me to quit. My only problem is my ears - a strange thing to say, but true. During the last ten years, I stretched my earlobes, and don't fancy getting a finger though them during training and having my ear ripped off. Thus I will have to retire the stretches, but don't know if they will shrink enough. If yes, then all is well and good, and off to judo I go. If no, then I have lost my stretches (harder than you think- they become part of you, literally and figuratively) and still no judo.
It's quite a dilemma for me.
