Damn, I'm out of shape

After a weekend of debauchery (well, two very good parties, at least), I decided I'd try and get a bit of exercise, and it being a beautiful spring day, I decided rollerblading was it. Damn, twenty minutes of not overly intense (pretty consistently moving, but not pushing it at all) and I'm tired. So, I'm definitely going to have to start doing this far more regularly.

So, anyone interested in semi-irregular rollerblading? Or maybe bicycling? (Yeah, I have to get my bike out of the garage and back on the road, too.) Cause, it will be easier with encouragement/companionship.
