Kami Semick and Nikki Kimball training in the Marin Headlands, demonstrating the Resilient Runner strength program

Resilient Runner is built around a single idea: run span. The number of years you can keep running well — pain-free, powerful, and adventurous — is not fixed. It's a function of the strength, stability, and resilience you build alongside your mileage. This program is the strength side of that equation.

Every session targets the structures that fail first in midlife runners: hip stability through the gluteus medius, shock absorption through the posterior chain, and postural endurance through the deep core. It's the program we use ourselves to keep showing up at championship races into our 50s, and the one we wish we'd had in our 30s.

This is for you if…

  • Recreational and competitive runners of any pace
  • Walk-runners and trail hikers building back capacity
  • Women returning to running after pregnancy, injury, or a long break
  • Adventuring women whose sport puts repeated impact through the body

What you'll build

Hip and pelvic stability

Targeted glute medius and deep hip work to keep your pelvis level and your knees tracking through every stride.

Shock absorption

Posterior chain strength through the calves, hamstrings, and glutes — the system that protects your joints from impact.

Postural endurance

Deep core and upper back work so you stay tall in the last hour of a long run, not folded over.

How it's structured

  • Two to three strength sessions per week, 25–30 minutes each
  • Each session: three primary lifts (squat or step-up, hinge, press or pull) and three accessory movements
  • Programmed to complement, not compete with, your run schedule
  • Built-in deload weeks so you can stack it with race blocks

What you'll need

  • Dumbbells or kettlebells (a range of weights)
  • Resistance bands
  • A step or low box
  • Optional: barbell for heavier squat and hinge work
From Nikki and Kami

Between the two of us we have a 100K World Championship, three Western States 100 wins, a UTMB title, and a Marathon des Sables win. We did not get there with random core circuits. We got there by treating strength as the foundation of running, not the afterthought.
