Strength training for running economy: what to do (without ruining your runs)

Topic

Strength training for running economy: what to do (without ruining your runs)

Summary

What this changes

• • Strength work can improve running economy and reduce injury risk when it’s minimal and consistent.
• • The goal is force and tissue tolerance, not soreness.
• • Two short sessions per week is a strong default for endurance athletes.

Protocol

A practical starting point

• • Do 2 sessions/week, 25–45 minutes each, for at least 8–12 weeks.
• • Prioritize a small lift menu: squat/hinge, calf raises, single-leg work, core/bracing.
• • Keep reps moderate and stop shy of failure to avoid trashing run quality.
• • Add short hill sprints or strides 1–2×/week if tolerated (low volume, high quality).
• • Deload every 4th week if fatigue accumulates.

Fit

Who it may help, and who should be cautious

Limits

Limitations and uncertainty

• • Many studies vary widely in exercise choice, intensity, and athlete level.
• • Strength improves economy indirectly; it won’t replace aerobic volume.
• • Technique matters: poor lifting can increase injury risk.
