Getting Started at SOS is Easy
Find Your Best Place to Start
Whether you’re looking for adult training, personal training, or sports performance training, we’ll help you determine the right next step.
Adult Group Training or Personal Training
Getting started with fitness shouldn't be a guessing game. At Skill of Strength, we've always believed that joining a gym should be more than filling out a form, picking a membership, and hoping for the best.
That's why everyone new to our adult training program or personal training start with:
- 1 Strategy Session + 2 Classes Within 7 Days
Your Strategy Session is an opportunity for us to sit down and get to know you. We want to make sure SOS is a great fit for you and help you build a successful training routine.
For $99, you'll receive:
- A personal strategy session with one of our coaches (includes a movement screen)
- Two classes to experience Skill of Strength*
- Guidance on the best path forward based on your goals and needs
Instead of simply dropping into a class and hoping it's the right fit, we'll take the time to get to know you and help you find the best place to start.
Youth Sports Performance Training
Trying out a free COMPETE or PERFORM class is a great starting point and you will leave here with a great idea of what it feels like to train here at SOS. Expect to spend about an hour at the gym for your class.
How it works
- Register here for athletes 12+.
- Schedule your visit with us via email or text.
- Arrive a few minutes before class starts and check-in on the iPad at our front desk (you'll already have a reserved spot.)
- One of our coaches will greet you before class starts.
Prerequisites
Whether you are a seasoned athlete or it's the first time you have ever stepped foot in a gym, this is a great starting point for most people. We do ask that you are not currently injured and are cleared for exercise.
After Your Class
We will follow up with you to determine the next best steps based on your goals, needs, schedule and fitness level.

Questions? We (probably) have the answers!
