We've started a thing this week at work where we something simple like pushups and dips, or planks, etc every couple of hours during the day (so we do it 7 times). It's just body weight stuff, but gonna see how we go keeping that up every day. Combine that with eating healthy up here and playing an hour of squash each night should see some benefit. It's good though, coz there's 3 of us in our office and we're all committed to sticking to it, so that helps.
