Why would a physician who understands the human body still hire a personal trainer?
Dr. Jason Littleton sits down with his personal trainer, Harrison Berezansky, to discuss how proper movement, strength training and accountability can improve energy, performance and quality of life—especially as we get older.
Harrison shares how his experience as a college baseball player led him into personal training and explains why building strength requires more than lifting heavier weights. Proper form, mobility, recovery and consistent programming all matter.
In this conversation:
- Why workout form matters before adding intensity
- Five foundational movements everyone should assess
- How improper technique can increase injury risk
- Why two consistent workouts can beat an unsustainable “no days off” plan
- Strength training for busy professionals
- Preparing the body for skiing and recreational activities
- The relationship between mobility, flexibility and pain-free movement
- Why small wins create lasting transformation
- The importance of nutrition, hydration, sleep and recovery
- How a personal trainer provides instruction and accountability
Harrison currently provides in-person training at Life Time in Winter Park, Florida. Local members can find booking information through the Life Time app.
