Episode 39 Kinda Strong, Kinda Fast: Why Runners Need Strength Training
New episode every Friday | Powered by Upward Running | Where Faith and Fitness Meet
In this episode of the Kinda Fast Podcast, Claire is flying solo while Travis is away at a conference, and she is joined by special guest Jon Beasley, owner and founder of Mind and Body Strength.
Together, they tackle a topic many runners avoid or misunderstand: strength training. They break down what hypertrophy actually means, why lifting does not automatically make runners bulky, and how strength training can help runners get stronger, more efficient, and more resilient.
The episode also includes some lighter running news, including the viral “churn and burn” butter-on-the-run trend and an update on the Shanghai Marathon’s progress toward World Marathon Major status.

- Deep Dive: Why runners need strength training with Jon Beasley
What Does That Even Mean? Hypertrophy
This week’s term is hypertrophy, which simply means building muscle size. Claire explains that hypertrophy is not the same thing as just getting stronger. It refers specifically to growing the muscle.
For runners, that distinction matters. Strength training does not automatically mean getting bulky. Building significant muscle size requires very specific training and nutrition, and most runners who lift are actually training for strength, efficiency, and durability instead.
Running News
- Churn and Burn: Claire shares the bizarre viral trend of runners making butter while they run by carrying heavy cream and salt in sealed bags inside their running vest.
- Shanghai Marathon: The Shanghai Marathon has passed the first stage of evaluation and is now one race away from potentially joining the World Marathon Majors.
Deep Dive: Why Runners Need Strength Training
Claire sits down with Jon Beasley, owner and founder of Mind and Body Strength, for a deep dive on how strength training supports running performance. Jon shares his background in coaching, strength training, nutrition, and helping people create lasting health and fitness habits.
He explains that strength training helps runners by improving running economy, increasing force production, strengthening joints and connective tissue, and making the body more efficient with every stride. According to Jon, runners who skip strength work may be leaving performance opportunities on the table.
The conversation also explores four major components of endurance performance: VO2 max, lactate threshold, running economy, and fuel utilization. Jon explains that strength training has its biggest impact on running economy by improving neuromuscular coordination, tendon stiffness, posture, and overall efficiency.
They also talk through how runners can begin adding strength training without overdoing it. Jon recommends keeping running as the primary focus when race training is the goal and using strength work as a secondary tool. He encourages runners to focus on lower volume, heavier lifts, fewer reps, and good fatigue management rather than high-volume bodybuilding-style workouts.
