I recently purchased the SPORT Band because I was getting so uncomfortable when I worked-out/bounced around. I do crossfit and even the dynamics/warm up were getting painful at 23 weeks. I'm now able to jog, jump rope and lift pretty comfortably. I really like that there are two adjustments. The first when you put the main wrap on, but then the two side velcros can be loosened or tightened as need during the workout without having to stop and remove the whole thing. Whatever kind of magic velcro used is awesome too! It's not hard to adjust, but also feels very secure. I wish I would have purchased it early, maybe around 19 weeks or so. I'm 5'6", pre-pregnancy 134 and now at 23 weeks weigh 144. The medium fits great.
