Your Calves Handle 8x Your Bodyweight Every Stride. Most Runners Never Train Them.
A targeted foot and calf protocol built for runners. 2 sessions per week, 30 minutes each, with video demos for every exercise. Based on the latest tendon and plyometric research.
No spam. Just the plan + occasional training insights.
Free. Instant download. Video demos included.
What You Get in 6 Pages
Two complementary sessions per week
Day 1 and Day 2 target three specific training qualities: tendon stiffness (isometrics), reactive stiffness (plyometrics), and raw calf strength (heavy loaded raises).
Video demos for every exercise
Clickable links to form walkthroughs so you see exactly what each movement looks like. No guessing on technique.
Coaching cues built into every exercise card
Key technique pointers (ground contact time, foot position, push cues) are written directly into each exercise. Not a separate instructions page you'll lose.
Running economy improvements backed by research
Heavy calf training has been shown to increase Achilles tendon stiffness in trained athletes, alongside improvements in running economy. A stiffer tendon means less wasted energy per stride.
Progressive loading guidance
3-5 reps in reserve (RIR) on every loaded exercise. Add weight when all sets hit the top of the rep range. Simple rules for long-term strength development.
Built for Runners Who…
Run consistently but have never directly trained their calves and feet.
Have dealt with Achilles tightness, calf strains, or lower-leg fatigue in the final miles.
Want better late-race durability and lower-leg capacity without adding another hour to their week.
Already strength train but skip dedicated calf and foot work.
The Science Behind This Plan
This protocol was built by Jonah Rosner, former NFL sport scientist, using the latest research on tendon adaptation, plyometric training, and calf strength for runners.
The calf-Achilles complex can contribute up to ~50% of forward propulsion in running, yet most runners never train it directly.
Used by 3,000+ runners and refined based on feedback and current research.
