1. push-up, this simple movement will improve your pectorals (chest) muscles, triceps, and deltoids (shoulder)
2. pull-up & chin-up, this breath taking movement very good for your shoulder, abdominal, biceps, and chest
3. sit-up, leg raise, crunch, and reverse crunch for a better abdominal muscle
4. squats and jumping jacks (aka skot jump in indo), this is what you need for lower body, for a better thighs, hamstring, and quadriceps.

and my advice is always keep do cardio (walking, running, cycling, swimming) to keep your calories intake < outtake
