Q: I have had a partial gastrectomy. used to weigh 67kg, now only weighs 48kg - with NO buttocks. I've tried a few simple excercises, because I am not too strong yet. What kind of excercises will get rid of this sagging bottom? Thanks for your input

A: You really should be working closely with a doctor and/or a physical therapist to put together an exercise program that's appropriate for your present condition if you're still recovering from the operation. On the whole your goal for now should be just getting your strength back. Once you've recovered as much as you're going to recover, you would probably want to start eating a little more and pick up exercise intensity (lift heavier weights that you can literally only lift 6-12 times before needed a rest). To start filling out your butt (in addition to eating more, of course) you will want to focus on big lower body exercises like the squat and the lunge. You can find both of those described in my essential exercises page. You can choose from any of my other programs and simply add a few sets of these lower body exercises while dropping the same number of sets of some upper body exercises. This, combined with eating more, will add some fat and some muscle to your buttocks filling them out.

But again, do NOT jump to intense exercise programs like that without consulting your doctor and start any exercise program gradually and learn good form before trying heavy weights. Best of luck to you in your recovery!
