How Many Calories To Burn At Gym?

[HDRIDER925]

Just wondering how many calories people burn when at the gym on tred mills, bikes or elliptical ect. How long should I stay on cardio since I'm trying to lose a beer belly/belly fat. Like this morning I did the tred mill for 16 min and burned it said 140 calories, later in the day elliptical for 10 min and 90 calories and I walked at home for like 45 min.

I would try to cut back the amount of calories you take in a day to begin with and then maybe shoot for burning 200-300 calories on the treadmill but also incorporating some weight training or ab workouts.
