New to Functional fitness?

No Experience Needed — Just Show Up

Starting something new can feel intimidating, but you don't need to be fit before you begin. At Rittenhouse Fitness, our coaching team meets you where you are and helps you build confidence, consistency, and real progress from day one.



Every workout is scalable to your current fitness level, whether you're brand new to training or returning after time away. Our Fundamentals program focuses on coaching, movement quality, and creating an environment where you feel supported, not judged.

What You Can Expect

  • Coach-led training every class, adjusted to your fitness and experience level
  • Guidance on movements, pacing, and technique at your own pace
  • A supportive community focused on consistency, not competition

I decided to try CrossFit for the first time ... They couldn’t have been nicer. I felt very welcomed and they helped me through everything. I’m seriously considering CrossFit instead of conversational lifting and this place would be a great fit. If you’re considering CrossFit or looking to switch gyms definitely give this place a try!!

Very friendly cross-fit box! I'm here 1 week for business (living in Switzerland), and found you on Google.


It was easy to drop in, and the session was just perfect, both dynamic and fun. I will recommend you everywhere I go!

I dropped in once while I was briefly in town and it was fantastic! People were friendly, and made some dinner recommendations after class. The coach was great, made some very helpful comments on my form. The class was small- you have to reserve your spot ahead of time- which allowed the coach to be attentive to all the athletes! I had a great time here and I would definitely drop in again if I were back in town.
