pilates is definately not a "fad' ......done properly you should not end up with a sore neck, back etc., in fact it has really helped me when I did have back, neck problems. As far as making your body look great, of course you have to watch your diet and try to eat healthy amounts of good food, but believe me, it can improve the look of your body. In my case I'm positive, because a long time back I was doing it and no other real work outs of any kind ...just pilates and correct foods and walking. I got stronger, posture improved alot, and my shape changed, meaning much nicer defined waist etc.....it does improve core strength. Now I run alot and do other forms of working out as well, but pilates will always be something I include....also my chiropractor who is also a certified personal trainer highly recommended it to me. I actually haven't even had to have any chiropractic care in over 2 yrs, and I'm convinced the pilates strengthening has played a big part. I'm sure like anything else, it isn't for everyone, but I think it would be a shame to turn people off pilates before they give it a try.
