An interesting new way of doing the gym

Ok, time goals don't work for me. The whole "I'm going to go do 30 mins on the bike" doesn't work. The new plan is to have the machines at the gym tell me I burned calories equal to whatever my dinner was that night. So last night I had a 700 calorie dinner. At the gym, I did my 20 Run(2 miles) and the treadmill claimed I burned 340 calories. So that meant I needed 360 burned on the stationary bike. It took me 41 minutes. If I eat less, I don't have to work out as much. It should keep me in steady weight loss. We'll see. At least it means I do varied amounts of cardio nightly, and not the same thing for the same amount of time every day, which gets boring and burns you out.
