I've been lifting on my Schiek belt for a couple of months now, and am a big fan. It is very comfortable and seems to give me all the support I need.
The size issue is real though--I have a 33-34 inch waist and I had to return the medium to get a small! I feel like Schiek is one of the women's stores that relabel all their clothes down a size or two so their customers will feel less fat. I guess Schiek trying to make us feel less fat?
