 As I age, I'm increasingly aware that I have no idea how well my muscles are working, or why I sometimes pull my back so bad it takes a week to recover. So I headed to the Mandel School in upper Manhattan to meet with Athos, a startup building high-tech workout gear that looks inside your muscles and analyzes the way your workout is going in real time. To help me test them was Jermaine O'Neal, six-time NBA All-Star and investor in Athos. Being involved with Athos is something I really believe in because it puts your health and your entity in your own hands. You understand the body better, you understand when you're doing exercise and things are not working as well. It basically tells you. We make workout apparel much like other companies, and that was always the goal was how do we make normal shorts and let's reverse engineer the technology into them. So it uses a science called electromyography, or EMG for short. Basically what that means is that we record the little electrical signals your muscles produce and we can tell how much of each muscle you're using. So we're able to translate in a way where you can pick up your phone and say, got it, and go back to what you need to do. Naturally I proposed a quick game of one-on-one. I wore the Athos gear for our basketball game and a quick weightlifting session. I was very impressed with how detailed the data was and how easy it was to interpret. On the squats, for example, I could see that I was using one leg way more than the other, and also notice how changing my form impacted which muscles were being activated, allowing me to better balance the stress on my joints. And if you're in the gym, take the squat example again, and you can look like you have the best form in the world going down perfectly straight, but when in fact you're using the right side more than the left, or using all quads and no glutes, you're not getting the benefit. We take a summary of what just happened and show you that heat map of the body and then show you muscle by muscle by the specific number how much you actually work each muscle. What this enables you to do is have a virtual personal trainer on your phone that can instruct you every step of the way. I thought the core values of what this brand represented is something that I went through a lot as a pro athlete. I had a lot of struggles later in my career with trying to figure out how my body was starting to break down. Being able to understand the body, understand the chain reaction, how the body ties in to itself. You take a brand like Athos, it tells you that, versus having to go and see different people to try to figure that out. So it's definitely something that I really believe in, not only as a professional athlete, but as a parent as well. For now, Athos seems best suited to professional athletes who are performing sets of weightlifting or weight bearing exercises and want to perfect their form and avoid injury. In the future, I could see them being integrated into everyday clothes and helping me to measure how well my muscles were working as I climbed the stairs to work or head out for a quick bicycle ride to the grocery store. It would definitely improve my performance and maybe help me avoid injury. They aren't going to transform me into a professional caliber athlete, but hey, a guy can dream, right?
