I have a client who is 125 lbs with 25% body fat, she is toned and lean except for her mid section. We do Pilates ab series and other Pilates excercises, ab machines, crunches, full sit ups with weights, and we’ve gotten into hoola hooping, still this is where most of her problem area is. Are there any different things we can do? Or some dietary change that may help?
I have a few comments here: 25 % body fat to me is not ‘toned and lean’. Depending on her age, it may be quite acceptable but I would not expect to see a defined midsection which she obviously would like.
What I would start with is a cardiovascular program, and then maybe some OVERALL weight training instead of all the stomach exercises. While doing all those crunches may be tempting but you may only end up building muscle mass in an area where you client does not want it (abs) while accomplishing nothing because spot reduction does not work.
This would be my course of action rather than looking at dietary changes. Those may be necessary if your client needs to lose weight but that does not seem to be the case if I interpret your description correctly.
