You will have your own treadmill and will be instructed on how exactly how to do focused, 30-minute intervals. You will feel breathless and stronger with each interval. Then, grab a pair of dumbbells for 30 minutes of muscle work that will challenge you by doing one-minute intervals. Next, off to the TRX Suspension System where you will have to stabilize with your core-this is most people's favorite of the program.

Last but not least, over to the rowers and 10 minutes of non-stop rowing with great technique challenging every muscle in your body.

This workout burns more calories than anything else you have ever done.
