Build Sports Performance Lab & Physical Therapy
We are all built to move, but when the geometry and balance of the body falls out of alignment, movement becomes difficult and less fluid. Misalignment causes deficits in some areas, leading to over-compensation in others. To get to the bottom of knee, back, ankle, hip, or shoulder pain, we combine our 30 years of clinical PT experience with state-of-the-art biomechanical analysis systems.

We'll use the data we collect as the basis for a game plan to help you to address biomechanical issues. Then, we are able to correct improper form, and optimize mobility while strengthening flexibility and neuromuscular control and power. We observe your pedal stroke, seat and arm positions to find patterns specific to your flexibility, strength, joint mobility, and neuromuscular control.

Alexander is brilliant. As a competitive ultra runner, I've been fortunate to have trained with a couple of world class coaches and I'd place Caitlin at the very top. Sue is superb physical therapist who really listens well and understands the spine really well. I've always received the best dry needling for my low back and cervical spine from her - better than I've ever had from any other PT.
Using 3D technology and years of professional experience, we are able to analyze a cyclist's movement patterns on and off the bike to determine if the bike fit is appropriate for his or her movement needs, contributing to pain on the bike, and/or affecting performance.

We then build an individualized movement strategy and plan, specific to the cyclist to protect against future injury, resolve a current injury and/or develop the performance needed.We perform a thorough physical assessment of the cyclist to analyze his/her movement patterns, strength, flexibility, joint mobility, and neuromuscular control.

I've been going elsewhere for PT/massage/chiro all summer. I came to see Larry for a bike fit and ended up having him work in some PT as well. I really wish I had come sooner. I more or less have none of the issues I've been getting worked on all summer, after just two appointments with Larry. I cannot recommend him enough. Thank you again for getting me out of chronic pain! My bike is also riding much more ergonomically and I have been very happy with that service as well

The staff and therapists are all top notch! A quality PT option in Louisville with a satellite location in Boulder. Their appointment booking website makes it effortless to book or cancel an appointment in 30 seconds.
They offer a wide variety of services from PT, massage, all the way to running gait analysis and high quality bike fits.
Dr Caitlin Alexander is a life saver. Her thoughtful approach and knowledge has saved my back and shoulder from tremendous pain and has got me back into racing again.
Their only possible downside (from what I understand) is that they dont handle insurance of

Working with Dr. Caitlin Alexander for PT has been fantastic so far. I’ve suffered with PF for over two years now and seen other PTs with no last symptom relief. Dr. Alexander looked at underlying issues and is working with me to treat my whole athletic self rather than simply the symptoms and this has made a world of difference. Caitlin is the best PT I’ve seen and I highly recommend her if you’re an athlete and struggling with injury!
I’ve also seen Jess for massage therapy and she is fantastic. It’s so difficult to find a massage therapist that understands athletic massage and actually

Great experience getting a running gait analysis! I am a professional triathlete and learned tons about how to improve my running economy and prevent injuries. Dr. Culbert is professional as well as fun to work with.

Build is the most fantastic place! Working with Sue for PT and Evan for bike fitting, I feel like I have a team that looks at more than just symptoms. They are extremely detailed, interested in your history, current treatment, and your goals! If you're an athlete of any scale and want a friendly shop that will look at the whole picture, Build is the place!

My son and I have had many many bike fits over the years. Hands down Dr. Meyer is the best! Incredible knowledge, technology and an amazing guy. Couldn't be happier with Build Sports Performance Lab!
