Review on MARAKYM Adjustable Clavicle Posture Corrector - Under Clothes Back Brace for Women & Men, Straightener for Spine, Neck, Upper & Lower Back Pain Relief - Shoulder Harness for Improved Posture Support by James Hounds

Pro later - I have a very bad stoop. I haven't worn it every day (I train up to 2 hours a day according to the instructions) but I've already noticed a difference. I still don't have the best posture/posture naturally, but now it's much easier and much more natural. If I keep using the product I am sure my posture will improve. Cons: There are other reports that it is uncomfortable. You should be really uncomfortable (if it was comfortable/natural you wouldn't need the product). However, the straps are relatively thin and made of coarse material, so that even with a shirt they seem to cut into the skin in places. The problem of rubbing in the skin is particularly relevant at the point of connection of the straps. There are other products with wider straps and joints. I recommended these products to my brother.
