Excellent workout, if you like the treadmill and rowing machines. In addition to those machines a variety of other equipment is used such as TRX bands and dumbbells. Everything is tied to interval training to keep your heart rate elevated. Myself though I dreaded the treadmill and I'm not a huge fan of the rowing machines. For that reason I put in for a cancellation. The agreement calls for cancellation at least 30 days in advance of your next charge, which I followed. I sent in an e-mail noting I was cancelling and today I've noticed that they again charged my credit card. I called and the receptionist stated that I needed to "fill out cancellation papers" I'm waiting for a call back now. Previous reviews I have read indicated that other locations make it hard to cancel. Some people have indicated that they follow the same model as Massage Envy (which the founders of Orange Theory Fitness are part of I believe) in relation to cancellation being a hassle.
