fitting exercie into normal life
Easiest way I know to get exercise is to cycle or walk briskly whenever possible and not to use public transport or car for journeys under 2 miles (30 mins walk) unless carrying something heavy or bulky and then can walk when unencumbered if delivering / collecting. Routine journeys to / from work, shops, cinema, etc are my main ways of getting exercise, plus canoeing (40 mins round trip by bike to club house, then usually about 1 hour paddle up then downstream), orienteering (usually have to drive, but some summer events are reachable by bike, and a race involves several kms running / fast walking), geocaching (by bike and foot), marshalling on adventure races (lots of walking / cycling to checkpoints and moving heavy kit eg kayaks at transistion areas) etc. All very cheap and mostly fun. We did use a free gym pass from a friend to go swimming & use machines a few weeks ago - my partner wasn't too happy, though, as despite being fitter overall, he can't swim as fast as me (not sure why, but I swam a lot as a teenager when training for life saving, and he has less body fat than me)
