Strength Training for Runners: Reducing Injury Risk & Improving Performance

Many runners focus solely on logging miles. If you’re not including strength, mobility and other forms of training, you’re potentially missing a critical piece of the puzzle. From a physiotherapy perspective, strength training for runners is essential for improving performance, reducing injury risk, and building long-term resilience. In this blog, we’ll explore why strength training and exercises for runners matter and how you can incorporate them into your routine.

Why Strength Training Is Important

Running is a high-impact, repetitive loaded activity that places significant stress on the body (lower back, hips, knees and ankles). Each stride can generate forces up to 2–3 times your body weight, particularly through the back, hips, knees, and ankles. Without sufficient muscular strength and endurance, this load is absorbed by passive structures, which can cause increased risk of injury. Strength training can help better absorb these forces and maintain better alignment throughout your run.

Common Running Injuries:

• Runner’s Knee

• Achilles Tendinopathy

• Shin Splints

• Lower Back Pain

• Ankle Sprains

• IT Band Syndrome

Benefits of Strength Training for Running Performance:

Incorporating a structured strength training plan offers multiple benefits - a stronger body can allow you to run faster, longer, and with less effort.

• Improves running economy (use less energy at the same pace)

• Enhances power and stride efficiency

• Reduces fatigue during longer runs

• Improves posture and running form

• Lowers risk of overuse injuries
  

How Often Should To Strength Train?

• Ideally perform 2–4 strength sessions per week

• Focus on correct form and control rather than quick repetitions

• Sessions last 20+ minutes

Consistency is key—small, regular sessions are more effective than occasional intense workouts.

Common Strength Training Mistakes:

• Skipping strength training during busy training weeks

• Ignoring muscle imbalances

• Using poor technique or fast repetitions

• Progressing too quickly with speed, weight and exercise choice

Key Muscle Groups to Strengthen for Running

• 1. Glutes (Hip Stability & Power)

  Weakness within the glutes and hip can be a contributor to poor running mechanics and stability.

  Glute Strengthening ideas:

  • Glute Bridges

  • Hip Thrusts

  • Clamshells

  • Banded High Knee Marching

• 2. Quadriceps (Knee Support)

  The quads (thigh) help absorb impact and stabilise the knee joint.

  Quadriceps Exercises:

  • Squats

  • Step-Ups, Downs

  • Split Squats

  • Lunges

• 3. Hamstrings

  Hamstrings assist with deceleration and balance muscle function.

  Hamstring Exercises:

  • Romanian Deadlifts

  • Hamstring Curls

  • Single-Leg Deadlifts

  • Good Mornings

• 4. Calves (Shock Absorption & Propulsion)

  Calf strength is critical for absorbing load and pushing off efficiently.

  Calf Exercises:

  • Double-Leg Calf Raises

  • Single-Leg Calf Raises

  • Eccentric Heel Drops

  • Seated Calf Raises

• 5. Core (Stability & Posture)

  A strong core can help maintain alignment and reduces energy waste.

  Core Exercises:

  • Planks

  • Side Planks

  • Dead Bugs

  • Bear Crawls

  • Crunches

Final Thoughts: Build Strength to Run Better

Strength training isn’t just for high level or professional athletes, it’s essential for every runner as well as other dynamic sports. By improving muscle strength, stability, and control, you are more likely to run more efficiently, reduce injury risk, and enhance performance. If you’re serious about running, it’s time to treat strength training as a core part of your training plan and routine.
