Hello thank you for your great question. I think it's fantastic that you are eager to return to your fitness routine, as keeping in shape will maintain your results looking great. You may return to the gym after about 45 days, but avoid seated exercises, like rowing and cycling, altogether for 90 days, as your fat grafts are still taking "root". Lateral lunges, squats, sumo squats, step ups, dead lifts, single leg dead lifts, and reverse lunges will maintain the area nicely. You can begin by doing high reps no weight, then gradually incorporate weights as you decrease reps. Your abdomen will get a work out, especially from the step ups without the need for getting down on the floor or laying on your behind. Good luck!
