I’ve heard of many positive results from using the weighted vest. After researching, I thought the best one was the Hyperwear Fit. My doctor said the vest should fit snug, not wiggle around, and she said start with 2 or 4 pound weight and slowly build up to 10 pounds. Too much weight can be damaging to bones… granted this is her advice for me and I’ve already experienced a spine fracture in the past. I just purchased the vest but haven’t had a chance to use it yet… partly due to laziness, and that the weather here is super cold, and had snow at the moment. But I’m really looking forward to using it!
