I'm too knackered to exercise in the evening and struggle getting up in the morning as it is never mind getting up earlier to exercise. Someone in my office mentioned that the gym 5 mins away does 30 minute lunchtime classes. If I did this 3 times a week (high intensity type classes) would it make any difference? Currently doing pretty much nothing. I'm so unfit I would sweat buckets so definitely need a shower, though I don't wear much makeup or have to wear super smart suit etc to work. For those of you that exercise in your lunch hour, is it a massive faff and is it worth it? Any tips for getting organised?
