would cardio or pilates be more effective?

which is better for losing about 15 pounds and getting a flat stomach?
- burning 1000 calories doing cardio at the gym
- burning 500 calories doing cardio at the gym, and burning about 200 calories doing a pilates class












i would say burning 500 during cardio and 200 during pilaties because you need cardio to burn of fat and lose weigh tand pilates tones you up
It is all about the calories you take in, and how many you burn.
To burn the most calories, just go running. Pilates is kind of a sham, although I guess it gets the job done eventually, too.
If you want to lose weight and get a flat stomach: eat less, run more.
