wellness at work

I have started taking advantage of a new state agency policy that grants us 30 minutes 3Xs a week for any wellness activity. My co-worker and I have been doing a 20-25 minute workout M/W/F for the last couple of weeks.. its going well. I usually eat lunch at my desk so I can leave early to pick up Roman. but this new short workout gives me a boost to make it thru the afternoon. our workouts vary from doing core work, to walking/running,.. we are going halfsies (sp?) on a medicine ball so we can really do some ab work......
