Since last summer a group of us have been getting together once mostly twice a week to "do" Harvard stadium. There are 37 sections, and with our team it now takes about 45 minutes to complete. It is so nice to be outside , chat while "sucking wind" and get a great workout in. We've even got a team together for the American Lung Association Climb in Feb '10- to race up 1 Boston Place.
Someone came up with the idea for a rogue bootcamp- where we meet on a gym floor about once a week. workouts include: sprint, tons of lunges, pushups, abs(including planks), and whatever fun exercises someone brings.
Every Sunday, I send an email to the group explaining what my workouts will look like for the week, if anyone wants to join.
