• Growing Up Playing Volleyball, Swim and Track...

  • From rotator cuff injuries, knee and hip strains and ankle surgery...

  • I knew there had to be something better...

  • So through education, passion and learning to rehab previous injuries on my own....

  • PREFORM WAS BORN. A place where former athletes know how to manage pain, perform like an athlete again and enjoy the hobbies they love.

  • Founder and Head Coach

    Former injured athlete to strength and conditioning coach and rehab specialist.

  • Pain does NOT have to be your reality after sport

    The tendonitis, the icing, the stress, ect. That was my reality during sports.

  • Recover doesn’t mean life without pain…

    It means knowing how to manage pain, while enjoying hobbies and still performing like an ATHLETE.

I’m Sophie Bartels, founder of Bartels Fitness and creator of the PREFORM App.

I grew up playing volleyball, swimming, and running track — constantly chasing performance, but never taught how to recover or rebuild properly. Years of overtraining, surgeries, and pain shaped my journey into what I now coach today: bridging the gap between prehab and performance.

After years in the strength and conditioning field, I realized that most former athletes don’t need more intensity — they need structure, support, and a coach who understands pain, plateaus, and the drive to move like an athlete again.

My mission is to help you:

  • Relearn how to move without fear

  • Build strength that lasts beyond the gym

  • Integrate performance with longevity

  • Reconnect to the hobbies and adventures that make you feel alive

I believe training is more than reps — it’s rebuilding confidence, athleticism, and identity through movement.
