Leg exercises for running faster: strength moves to boost speed
Runners spend endless hours on mileage and pacing, but the fastest gains often come from the weight room. A 2021 meta-analysis found that just two sessions of plyometric training per week improved 5K times by roughly 2.5% [1]. That's not about grinding out more miles; it's about targeting the right leg exercises, single-leg deadlifts, Bulgarian split squats, and calf raises, that directly translate to stride power and efficiency. Most runners ignore this, focusing on endurance while leaving speed on the table. Dorsi builds these sessions into your week based on your recovery data, so you don't have to plan them. The exercises below cover the specific movements and why they work for faster running, no fluff.
Practical Playbook
Build a base with heavy compound lifts
Slow heavy squats build the raw force production your stride depends on. Leg presses are fine but they don't teach your hamstrings to fire with the glutes the way a barbell squat does. Aim for 3-5 sets of 5 reps at 80% of your max. Deadlifts too. Two heavy days a week, no more.
How often should you do plyometrics?
Twice a week max. Plyos like box jumps, bounds, and pogo hops train your nervous system to snap through the ground quickly. Too much volume and your connective tissue nags. Start with 3 sets of 5 explosive reps on a 12-inch box after your warmup. Fresh legs only.
Don't skip single-leg work
Running is a series of single-leg hops. Bulgarian split squats, reverse lunges, and single-leg RDLs fix strength imbalances that slow you down. Do them after your main lift. Four sets of 8 per leg. Your non-dominant leg is probably weaker, so lead with it.
Finish with short hill sprints
Hill sprints combine strength and speed without the impact of flat-out track work. Find a steep 30-meter hill. Jog up, walk down, repeat 6-8 times. Do this once a week in your offseason. It builds power without wrecking your hamstrings. Progress by adding one rep each session.
Common Mistakes
- Mistake
- Only doing heavy squats and ignoring plyometrics.
- Why
- Heavy squats build raw strength but not the explosive power you need to push off the ground faster. Your stride frequency suffers.
- Fix
- Add box jumps, bounding, or pogo hops twice a week. They teach your legs to produce force quickly, that's what makes you faster.
- Mistake
- Neglecting single-leg exercises.
- Why
- Running is a single-leg sport, each stride you land and push off one foot. Bilateral moves like squats don't fix imbalances or train stabilizers.
- Fix
- Include lunges, single-leg deadlifts, and step-ups. Start with bodyweight, then add load slowly.
- Mistake
- Skipping calf raises for ankle stiffness.
- Why
- Weak calves and stiff ankles waste energy every time your foot hits the ground. You lose forward momentum and increase injury risk.
- Fix
- Do standing and seated calf raises 3x a week. Add ankle mobility drills like ankle circles and dorsiflexion stretches.
- Mistake
- Only focusing on quad strength, neglecting hamstrings and glutes.
- Why
- Overpowered quads relative to hamstrings create a muscle imbalance that can pull your pelvis forward and slow your stride. Hamstring pulls are common too.
- Fix
- Prioritize hip thrusts, glute bridges, and Nordic curls. Your glutes are your main propulsion muscle, train them like it.
