Strength Training for Runners: The Six Moves That Matter

Most of the running injuries I see aren't bad luck or bad form. They're a tissue that got asked to do more than it was built for. Strength training is the cheapest, most reliable way to raise that ceiling. It can make you faster, too. If I could add one thing to every Brooklyn runner's week, it's this.

Why it works, in one idea

Running is load. Every mile is a few thousand foot-strikes, and each one asks your tendons, bones, and muscles to absorb and return force. Injuries show up when the load you pile on outruns the capacity of the tissue to handle it. Strength work builds capacity. Stronger calves, hips, and feet take the same mileage with room to spare. That means fewer breakdowns and better running economy, as research has found for years.

The core six

No gym or hour required. Six movements, twice a week, cover the tissues that break down most in runners:

• Split squats: 3 x 8 per leg
• Single-leg Romanian deadlift: 3 x 8 per leg
• Calf raises, straight and bent knee: 3 x 15 (the bent-knee version is the one runners skip and need most)
• Step-ups: 3 x 10 per leg
• Side plank: 3 x 30 seconds per side
• Single-leg glute bridge: 3 x 12

Lift heavy enough to matter

This is where runners undersell it. Light weight for high reps feels productive and does almost nothing for tendon capacity. Once your form is solid, work in a range where the last two reps are genuinely hard, and add load as it gets easy. Tissue adapts to the challenge, not to how virtuous the effort felt.

When to fit it in

Do strength on your hard days, after the run, so easy days stay truly easy. Twenty-five minutes is plenty. Two short sessions you actually do beat one long one you dread and skip. Consistency is the whole game.

If something already hurts

Strength is prevention, not a cure for a tissue that's already angry. Pain that's sharp, worsening, or stuck in one small spot is a signal to get it looked at, not to load through it. The Injury Clinic here covers the common ones and when to see someone.
