Jacob Coerver has been training St. Charles residents since 2018 — at their front door, on their schedule, with zero gym required.
St. Charles is where Fenix Fitness was born. This is home — and I've been training clients here since day one. The community that gave this business its start is still the one I care about most.
Whether you're in the Historic District, Frenchtown, or out near Cave Springs — I'm already in your neighborhood. No travel premium, no unfamiliar trainer. Just focused, one-on-one coaching at your front door with a program built specifically for you.

Monthly packages range from $75–$90 per session. St. Charles is home base, so you're typically on the lower end of that range. I'll give you the exact number when we connect.
Not a thing. I bring everything we need to your St. Charles home — weights, bands, mats, everything. All you need is a clear space and the commitment to show up.
That's exactly who I do this for. I was 200 lbs at 16 with no clue where to start — so I know what it feels like. I'll meet you exactly where you are and build from there. No judgment, ever.
The first session is always free. I come to your St. Charles home, learn your goals, and give you a full workout — no cost, no obligation, no pressure.
