"Stew is simply the very best fitness pro and strength coach I have worked with. I have done it all: Crossfit, EXOS, and worked with Special Operations fitness coaches. His expertise and approach are unsurpassed, in my opinion. Having worked with him both in the gym and, remotely, from afar, he is focused on individual needs, progressive and regressive, and steady progress!"

 Lieutenant General Kevin Mangum — U.S. Army Retired

"S2 training saved my life in more ways than one.  I became stronger mentally physically and emotionally. Not only did I change my body for the better ( losing almost 40 pounds of fat and gaining around 10 pounds of muscle; taking my body fat percentage from 36% to  18%)  but it made me more mindful and gave me the will power I needed to attend to other areas of my life."
