i wouldn’t reccommend it. it’l stretch out the material in the girdle and/or shaper.

I wouldn’t advise it, because it is constricting. To exercise you need a full range of motion to get the best effect of the exercise. You can’t do that with girdles or body shapers.

It could help your back BUT back in the day they had these fat giggling machines that did just that, giggled fat. It was a platform that you would stand on and a wide thick strap went around you back or stomach and pulled back and fourth in small fast motions, almost like you needed a hula hoop. When the fat loosens inside the body it is more apt to be shed through sweat or burnt calories. The more you move and giggle around the more fat loosens from the larger pieces and is lost.

It doesn’t help and isn’t advisable. You will want to wear clothing that lets your skin breathe and sweat evaporate. Plus I can imagine that it would be very constricting and uncomfortable.

If it interferes with your breathing or your range of motion it’s a bad idea. But I’ve read somewhere that having your muscles constricted slightly (by wearing spandex bike shorts or something that holds you in a little) helps your workout.

This link tells a little bit about the benefits of compression garments while exercising — it’s in PDF, and it’s a scientific article, but basically it says it helps prevent muscle damage and helps with recovery time.
