While we're on the subject of plus sized bras, I should add that there is probably no better investment or accessory to a comfortable weight loss workout program than a good-fitting and comfortable sports bra.
The popular plus sized sports bras shown above are from the ENELL line of sports bras. They are made from NATUREXX, which consists of 90% nylon and 10% Lycra fabric.
If you are more than a few pounds overweight, these bras will make your exercise routine so much more enjoyable. For me personally, my exercise usually consists only of regular brisk walking, but a sports bra still makes a big comfort difference even if this type of exercise is not the highly bouncy kind.
Personally I prefer sports bras made of at least 90% cotton. The one shown here is a full support cotton sports bra made by Grenier. But maybe that's because I haven't tried the high-tech new material bras yet. These materials promise to wick away moisture and keep you dry during workouts. They also supply significantly more support than cotton bras can.
