Redefining physical therapy
& personal training
Our staff is made up of physical therapists, kinesiotherapists, movement coaches and personal trainers that understand the huge gap between physical therapy and personal training.
Physical therapy traditionally focuses on your localized injury leaving you with fear to do anything outside of your rehab exercises.
Personal training is oftentimes a random workout of the day based on something the trainer just watched online with no focus on your personal needs.
Level 3 Fitness is focused on your needs to help you gain confidence, capability, and the capacity to enjoy Movement for Life.
The 3 Levels of Fitness
Through Movement for Life Classes, 1-on-1, or semi private sessions, we can help you through all three levels of fitness so that you can enjoy healthy Movement for Life.
The process of restoring tissues and systems to a healthy state. We have physical therapists and kinesiotherapists to help you with injuries and chronic issues.
The ability to actively produce or control movement. Our movement coaches help you restore your functional and foundational movements to allow you to return to the activities you love.
The capacity to exert or withstand force or pressure. Our functional exercise specialists will design workouts specifically tailored to help you excel at your activities.

Meet the Team
Doug Aylesworth, CPT, CAFS, CES
Doug came to Level 3 Fitness after becoming frustrated with the corporate structure at a “big-box” chain gym where the focus was on sales, not the client’s goals. His passion is to help his clients explore their path toward better overall physical and emotional health through movement.
Doug specializes in functional movement and performance. Doug is also certified as a Cancer Exercise Specialist which is an area that is very personal to him.
Before Doug and his wife started raising a family, he spent a good deal of his time training and racing in triathlons ranging from Olympic Distance to Ironman. But, now that they are busy raising two boys, his new ultimate endurance event is parenthood...where there is no finish line, the course changes everyday, and the physical, emotional, and psychological demands never let up...he's never been happier!
