Silver: The boot camp I do is indoors at the moment because it was over winter and even the instructor wasn't brave enough to be out in the pitch black and negative temps lol.
It's 3 mornings a week (6-7) and involves the usual interval training/running/jogging with a lot of conditioning/strength i.e. sit ups, push up, dips, squats etc etc etc etc.
I'm so buggered after a session! Ours is combined running and conditioning though...the only dedicated day we may have it when we do boxing for a session...love it!
I'm signing up for the spring session this week
