Trying to keep the fitness going at the moment and its paying off. I'm cycling 2-3 times a week plus swimming and climbing when possible (aim of once a week for each), however around trying to write my PhD getting out for a 1 or 2 hours each day just isn't always possible. Any suggestions for exercises around the home or for a short time period (say half an hour) to keep the strength/fitness up in between when I can get out?!
Cheers in advance to all the fitness monkeys.
Bear in mind, as a woman, 30 press ups is just not an option!
