The Best Strength Exercises for Runners (and Why They Matter)

Most runners are told to strength train, but few are told what actually moves the needle or why. The research picture is clearer than the gym-floor folklore suggests. Two things stand out: strength work makes you a more economical runner, and it is consistently associated with lower injury rates. This guide walks through the evidence, then gives you a compact, practical program built around the movements that carry the most weight. It is education and movement screening, not medical advice, and no exercise plan can promise to prevent or cure injury.

Why strength training matters for runners

It improves running economy

Running economy is how much oxygen you burn to hold a given pace. Two runners with the same VO2 max can perform very differently if one is more economical. A systematic review of trained middle- and long-distance runners found good evidence that strength training improves running economy, time-trial performance, and sprint speed, without harming VO2 max or blood lactate.[1] A meta-analysis of highly trained runners reported a large, unanimous beneficial effect on economy when strength work was added to normal running.[2] Reviews of concurrent training put the typical economy improvement in the range of about 2 to 8 percent.[4]

The mechanism is neuromuscular, not aerobic. Heavier, more powerful muscles and stiffer tendons let each stride return more elastic energy and recruit fewer motor units at submaximal pace. In one study of collegiate and national-level runners, maximal and explosive strength training significantly improved economy over 20 weeks.[3] Notice what these studies used: heavy loads and explosive or plyometric work, not endless light circuits. That distinction matters when you build a program.

It is associated with lower injury rates

A landmark meta-analysis of randomized trials across sports found that strength training reduced sports injuries to less than one-third, and cut overuse injuries almost in half.[5] A later review from the same group described strength training as a superior, dose-dependent way to lower the risk of both acute and overuse injuries.[6] These are associations from controlled trials, not guarantees for any one runner, but the signal is strong and consistent. For runners specifically, greater eccentric hamstring strength (built with movements like the Nordic curl) is associated with roughly halved hamstring injury rates in athletes,[7] and hip and gluteus medius function is repeatedly linked to running-related knee and hip problems.[8][9]

The best strength exercises for runners

Below is a core menu. Each movement earns its place by targeting the muscles and qualities that running demands: force production through the hips and knees, single-leg stability, elastic stiffness at the ankle, and a trunk that resists rotation. Pick a squat or deadlift variation, one or two single-leg movements, calf and hip work, an anti-rotation core drill, and a small dose of plyometrics.

Compound lifts: squats and deadlifts

Bilateral compound lifts are the fastest route to whole-body force. Squats load the quads, glutes, and adductors; deadlift variations bias the posterior chain of glutes, hamstrings, and spinal erectors. The economy literature leans on heavy loading, so work in the 4 to 6 rep range with challenging weight and long rests rather than chasing a burn.[1] If a barbell is not available, a goblet squat and a trap-bar or dumbbell Romanian deadlift cover the same ground.

Single-leg strength: RDLs and step-ups

Running is a series of single-leg landings, so single-leg strength transfers directly. The single-leg RDL is especially valuable: it hammers the hamstrings and glute max while forcing the small hip stabilizers to work, and eccentric hamstring strength is associated with roughly halved hamstring injury rates in athletes.[7] Step-ups and rear-foot-elevated split squats add knee-dominant single-leg force and surface side-to-side imbalances that a barbell can hide. If hamstring health is a concern, our guide to hamstring strains in sprinters goes deeper on eccentric work.

Calves, hips, and core

The calf complex is one of running's most important springs, so train both the gastrocnemius (straight-knee raises) and the soleus (bent-knee raises). For the hips, glute-medius strength and timing show up again and again in the running-injury literature: reduced gluteus medius activity is associated with patellofemoral pain, and hip abductor weakness is linked to several running-related injuries.[8][9] Side planks, banded hip abduction, and single-leg stance drills build that control. See our glute-medius exercises for runners for a focused routine, and runner's knee and patellofemoral pain for how hip strength ties into knee mechanics. Finish with anti-rotation core work like the Pallof press, which trains the trunk to resist twisting so more of your force points down the track.

Plyometrics

Plyometrics train the stretch-shortening cycle directly, teaching muscles and tendons to store and return energy fast. Meta-analytic evidence shows that a mix of resistance and plyometric work, done 2 to 3 times a week for 8 to 12 weeks, is an effective way to improve economy in trained runners.[2] Start small and springy: pogo hops, ankle bounces, and short bounds. Keep contacts low, land quietly, and prioritize quality over quantity. Because these are high-force movements, build a base of strength first and progress gradually.

How to program it into your week

Two sessions a week is enough for most runners and is the dose used in much of the research.[2][6] Keep the compound lifts heavy and the total volume modest so your legs stay fresh for running. A simple template:

1. 1Day 1 (strength focus): squat variation, single-leg RDL, calf raises, side plank or hip abduction, Pallof press.
2. 2Day 2 (power focus): trap-bar deadlift or hinge, step-ups, low-volume plyometrics, anti-rotation core.
3. 3Pair strength with easy running or place it on quality-run days after the run, never right before a hard session.
4. 4Progress by adding a little load or one set every week or two, not by piling on reps.

Strength is only half the equation. How you move at speed determines where those forces go. If you want to see your own mechanics, you can screen your stride with the CritchPitch Run Lab and use the results to decide which of these movements deserves the most attention.

Compared with running alone, strength training with heavy loads and plyometrics improves running economy in trained runners without compromising aerobic fitness.Synthesis of Blagrove et al. 2018 and Balsalobre-Fernandez et al. 2016
