If I don't go first thing in the morning then I don't go. DD1 is doing cross country training this semester on the days that I work so my swimming/gym is on hold because I need to take her while DH deals with DDs 2 and 3, but once she's done with that I will get back into it. To begin with I find it a pain to organise two sets of clothing etc, but once I'm in the routine I really love the feeling I have starting my work day having already done my workout.

A kazillion years ago the building I worked in had a public gym, so I would go and do something at lunch time. That was good too - made me actually stop work to have a break, but the downside was that I don't glow like ladies are supposed to - I turn beetroot red and sweat like a pig so going back to work I could still feel a bit grotty for quite a while, despite having showered.
