More gyming, I've found the cardio that works for me at the moment (about 30 minutes of fast walking, I hope to build up to a slow jog over a year or two). Yes there are better exercises for my weight, but I like the treadmill (and exercise bike, but I'm too heavy for spinning). While I'm in control I actually have to press the buttons to change the speed, which is just enough to stop me from slowing down.

Really the only annoyance is nowhere to take out my lens, which means either exercising without vision or not using the gym's showers. Which I haven't yet, but mainly because I keep forgetting my towel, thankfully my vision's not quite as bad as I've been claiming.
