Hi. We are SmartBodies. Nice to meet you.

We put the "personal" back into Personal Training.

Let me show you how.

Core values


Before the workout we strive to genuinely care about you and your goals. We customize your plan just for you. How can we possibly do this? We actually get to know YOU! From there we custom build your workout and diet plan for you from scratch!

We believe results are what separates good trainers from great trainers. Results take more then just the hard work you put in at the gym. In our over 30 years in business we've perfected a 3 step plan to optimize your results!  



During our time together we focus on you. We aren't glorified rep counters "crunches and curls" trainers. We focus on optimal training to get the most out of each rep.

After the workout we provide all encompassing diet and stretching instruction. We do this because we know your goal isn't to be the next Mr Missouri. It's to invest in your health, your quality of life, and your future!
