Strength Training for Runners

Strength training improves running economy — how much energy you burn at a given pace — even though it doesn't directly train the aerobic system. Stronger tendons and muscles store and return more elastic energy with each stride, which is part of why efficient strength work translates to faster times without more mileage.

It's also one of the best tools for injury prevention. Many common running injuries (IT band syndrome, patellofemoral pain, Achilles issues) are linked to weakness in the hips, glutes, and calves rather than to running itself. Two strength sessions a week addressing these areas meaningfully lowers injury risk.

You don't need a bodybuilding program. Compound lower-body movements (squats, deadlifts, lunges, calf raises) at moderate-to-heavy loads and low-to-moderate reps (roughly 4-8) build the kind of strength that transfers to running, without adding so much muscle mass that it becomes extra weight to carry.

Timing matters less than consistency. Lifting the day before a hard run isn't ideal, but lifting twice a week on non-key-workout days, year-round, beats an inconsistent 'strength phase' squeezed in once a year.
