Opex is exactly what I needed when Crossfit groups classes became stale. Mike knows my goals, plans my individualized workouts and nutrition to meet those goals, and pushes me to get more. And the numbers don't lie - numerous strength and time PR's since plateauing with other cross training.

I've worked with Mike and his crew for 4+ years. I continue to come back because of the personal training approach used at OPEX St. Louis. My program is tailored to me, my strengths and my weaknesses. I'm constantly learning and improving, all the while bettering myself. Grade A

Large gyms full of equipment I don’t know how to use and people who ignore more have always intimidated me. I didn’t know there was any other way to train though, until I met Mike and he introduced me to Opex. I LOVE that every workout is planned just for me, and the other gym members are real people I can relate to. The results and the scale do not lie!! This place is the BEST!
