Gimme a Break!

I'm taking a break from the fitness bootcamp. Was it too hard? Heck yah it was hard. One day the instructor started the class on a 20 mins jog at a pace of 5 mph with an incline of 15% and considering the practice of running backwards on the treadmill at a 4.0 mph pace or jogging sideways on the treadmill as breaks in the jog isn't my idea of your average workout. The last two weeks I've been exhausted all the time. Will I go back. Yes, afterall I have pre-paid for the session.
