H.S.
Pilates is incredible for strength, tone and stretch (fan of yoga too but always been more into pilates). Many (many many) moons ago I was a ballerina - with lots of ballet classes, walking (fast past) and pilates a few times a week my stomach was so flat it was ridiculous. More importantly than that my stomach muscles were so strong that when I had an ovarian cyst (size of a grapefruit), it was being pushed inward, couldn't tell at all from the outside when most people with a cyst that size would have had a bulge. When they went to remove it - under full anasthezia (spelling??) my incision was suppose to be about an inch, but they couldn't move my muscles so they had to make it about 4-5 inches! So YES pilates works!!!
