1. I regularly train on my indoor bike, which started out to lose weight, but now that that's done, it's mostly to improve my own records and stuff like that. Which are impossible to compare with anything other than my own bike, so it's purely a fight against myself (and the occassional time my girlfriend uses it to keep training when she's here, but I'm significantly faster).
2. Last summer, as in many years, I started running: walking/running/walking/running to slowly improve the amount of running time and decrease the walking time. For the first time ever I did not give up, managed to finally run 5km without walking in between and am now working towards a half marathon this summer. I've ran 5km in 24:25, 10km in 53:15 and 15km in 1:27.08, my longest run ever is now (since this month) 16km. Half marathon is getting closer and closer.
3. Just for shits and giggles I asked my girlfriend to train me towards being able to do 30 consecutive push-ups, which is quite a lot harder than I thought. I'm at 20 though, 30 should be in reach soon.
