[Obesity Discussion]

I don't see any exercises on there for back, biceps shoulders, hamstrings and calves. You should not forget about those muscles as well. Also, I would advise against repeating a routine like that in the same day. Do all your exercises for a specific body part one after the other. For example, don't do one chest exercise, work every other body part for 20 minutes, and then do another pec exercise, etc. Every few weeks I would switch up the types of exercises you are doing, the sets/repetitions, etc. I'm not going to go into too much detail, but you get the idea.

If you're trying to lose weight, you're only going to do so by burning more calories than you are consuming. That being said, it's difficult to build muscle as fast when you are burning more calories than you are consuming (known as a calorie deficit). The main benefit behind weight lifting while you're trying to lose weight is to keep the muscle you already have, as when you start to lose fat while trying to lose weight, you lose a little muscle with it.

If you want to lose fat in the tummy/hips/tights, a calorie deficit is going to do that a lot more than weight lifting....
