Alison Klaum, NASM CPT, CES

Alison is an NASM-certified personal trainer who specializes in corrective exercise and human movement. In addition to her Corrective Exercise Specialization (CES) through NASM, she has also received extensive training through the Brookbush Institute of Human Movement Science and is close to completing her Human Movement Specialization.

Alison works with older and special populations, particularly those who are recovering from injury or have neurological conditions such as Alzheimer’s and Parkinson’s. Because she also has several family members who have PD, she is particularly passionate about working with those who are impacted by the disease. Recognizing the importance of ground-based exercise and primal movements to improving human movement, Alison has also recently become a certified Animal Flow® instructor.

She is excited to bring her knowledge of this innovative, bodyweight approach—good for both the brain and the body—to PRT workshops. Combining her nearly 10 years of experience as an educator with a passion for human movement, Alison is honored to join the PRT Instructor team.
