Premium, science-backed training options for athletes at all levels. We specialize in creating more robust and well-rounded athletes.

This guy Jordan really knows his stuff. He improved my form, introduced me to new and ingenious full body activation movements, and helped me break personal goals I had for years. A true master of his craft. Plus he’s pretty big.



Jb Performance is great for all types of people looking to get into shape. Jordan goes above and beyond to help his clients and really makes sure to take extra time with each and every person. He provided me with great insight and the advice I needed to get into great shape!

I went to JB performance with the goal of improving my strength and conditioning. In just a short amount of time, I was noticing such a difference. As a 5´4¨ girl, I am lifting more than I ever thought I could. I also liked how they are flexible with my schedule and make it easy to get a great workout in.
