Who is

Aarin Walker?

Hello! My name is Aarin Walker the Founder and CEO of Strive 2 Fitness. I am a Mobile personal trainer, nutritionist, and fitness coach who is a strong believer in POSITIVE REINFORCEMENT and tough support (much different from negative reinforcement!). I always operate out of mutual respect to empower the everyday person to push past their comfort zone and toward a strong and healthy lifestyle.


Since I started this company in 2018, I have helped people lose weight, gain self-confidence, and improve their perception of exercise and proper nutrition. Call our office in Saint Louis, Missouri today and take 25% off your first session. Referrals are also greatly appreciated!

Mission Statement

My goal is to create a challenging workout and/or program that is both FUN and REWARDING! Working out can easily get boring (let’s keep it real!) so I like to challenge clients by working on different and fun exercises each time while creating fun (beneficial) rewards for clients as well.
