Not sure if this is the right place for this, but I was curious if anyone had any thoughts on Donnie Thompson's new product called the Bow Tie. For anyone who doesn't know Donnie Thompson, he's a big name in the powerlifting world, and he has put out a lot of mobility content that's been extremely helpful to a lot of powerlifters. The Bow Tie is basically a harness that crosses your upper back and around the shoulders, gently pulling the shoulders back encouraging a more upright posture. I noticed some improvement in thoracic mobility from the foundation and stretch series, but as someone who has spent most of my life slouched over a computer, I can use all the help I can get.
