I get to work & back on my bike, about 50 mins a day over a big hill.
I tend to go for a nice walk most lunchtimes, fairly brisk, about 45 mins with my audiobook.
Then when I get in I *try* to get on my cross trainer and aim for 20 mins, sometimes more sometimes less depending on stamina & how interested I am in my audiobook. Couldn't just exercise on its own without some other kind of entertainment to keep my mind busy! I used to do that but would get SO bored and then start to resent the 'wasted' time if that makes any sense?
Trying to get in a big bike ride most weekends (20miles+) although haven't had time this weekend or next... But that's cos I'm training for a charity ride in July, usually weekends are quite lazy apart from leisurely walks in the park or around town.
I still wouldn't feel comfortable going to a gym! Went into a local one to enquire about their yoga & pilates classes a few weeks back and was totally intimidated out of it...
