Movement as the Foundation of Health

Kristen Lettenberger is a Doctor of Physical Therapy and Master Coach with nearly 15 years of experience across physical therapy, strength training, and women’s health. Her guiding idea, “movement is medicine,” shapes her work with people who want to move better and live healthier lives.

A physical therapist coaches an adult woman through a gentle mobility exercise in a rehabilitation space.

Her approach reaches beyond general fitness. She supports women through pregnancy and postpartum, advocates for pelvic floor health in both women and men, and draws on experience in rehabilitation, sports, and powerlifting.

From an Active Childhood to Movement Specialties

Lettenberger’s interest in movement began in childhood, when she enjoyed climbing trees and riding bikes. She played travel softball in high school, spent time lifting weights, and later gained a deeper understanding of rehabilitation while working alongside a physical therapist.

That experience showed her how resistance training and rehabilitation can support each other. She chose a career focused on helping people develop useful strength and move with greater confidence.

Strength Training and Purposeful Movement

Her favorite exercises are strength-based movements with barbells or kettlebells. During her competitive powerlifting years, she concentrated on the deadlift, squat, and bench press.

A woman performs a controlled barbell squat while a spotter assists in a modern gym.

Lettenberger draws a clear distinction between working out and training:

  • Working out is often casual and lacks a specific focus.
  • Training is intentional and tied to a goal, such as completing a race, changing your physique, or setting a personal record.

For her, strength means being mentally and physically ready to meet challenges. She connects that idea to resilience in both heavy lifting and everyday life, including childbirth.

Training, Nutrition and Postpartum Recovery

As she rehabilitates after pregnancy, Lettenberger says her routine emphasizes enjoyment and recovery. She trains resistance and strength work at least four times each week and uses recovery days for mobility, pelvic floor activation, cycling, or walking.

Her nutrition approach centers on high protein, with a stated target of about 130 grams daily and a preference for complete animal-based protein sources. She keeps the diet flexible rather than strictly rigid.

For supplements, she lists a multivitamin, fish oil, creatine, and vitamin D. She also favors a branched-chain amino acid product and whey protein, including a flavor she likes mixed into coffee.

Building Fitness Habits That Last

Lettenberger’s advice for beginners is straightforward: prioritize consistency over motivation. Choose an enjoyable activity, such as a group fitness class, and begin with a manageable commitment, such as one workout each week.

Once the habit takes hold, she recommends building gradually rather than making an abrupt change. Her broader message is to avoid being overly hard on yourself while recognizing that steady effort creates a useful foundation.

“Don’t beat yourself up too much; it all works out in the end.”
