Will Strength and Conditioning Help My Running?

If you’re a runner, you might have wondered whether strength and conditioning is really worth your time. After all, running is all about moving your legs, isn’t it? Why spend time lifting weights, doing core exercises, or performing plyometric drills when you could be logging more miles?

The truth is that strength and conditioning can be a game changer for runners of all levels, from beginners to experienced marathoners. Done correctly, it not only improves running performance but also reduces the risk of injuries, helps you maintain good form for longer, and makes your training more enjoyable.

Today we’re looking at how and when you should add strength and conditioning to your running training routine, but first, a little more about why:

Why is Strength and Conditioning Good for Runners?

Running might look simple, but it is a complex, high impact activity that relies on muscles, joints, and tendons working together efficiently. Every stride engages multiple muscles, while your core stabilises your body, and your joints absorb repeated impact. If any of these areas are weak, you are more likely to tire quickly or develop injuries such as IT band syndrome, plantar fasciitis, or knee pain.

Strength and conditioning addresses these issues by:

Building Muscular Strength
Strong muscles make each stride more powerful and efficient. They reduce fatigue, improve endurance, and allow you to maintain pace over longer distances.
Increasing Muscular Endurance
Running, especially long distance, demands that muscles work repetitively without tiring. Strengthening them off the road helps delay fatigue during long runs.
Improving Running Form
Good form relies on strong glutes, hamstrings, core, and stabilising muscles. Stronger muscles help maintain proper posture, reduce excessive vertical movement, and improve stride efficiency.
Preventing Injuries
Strength and conditioning helps correct muscle imbalances, improves joint stability, and strengthens connective tissues like ligaments and tendons. This reduces the risk of common running injuries.
Boosting Metabolic Efficiency
Stronger muscles are more efficient at using oxygen and energy during exercise. This can help you run faster or longer without increasing effort.

Strength and conditioning work complements running. It is not a replacement for miles on the road, but it does help make those miles more productive.

Which Muscles Benefit Most from Strength and Conditioning?

Running uses many muscle groups, and targeted strength work can make all of them stronger and more resilient.

Lower Body Muscles

These are the primary engines of running.

Glutes: Crucial for hip extension, propulsion, and stabilising the pelvis. Weak glutes can lead to hip drop, knee pain, and inefficient stride mechanics.
Quadriceps: Assist with knee extension during push off and absorb impact on landing. Strong quads help reduce fatigue during long runs.
Hamstrings: Control knee flexion, support propulsion, and stabilise your stride. Strengthening them reduces the risk of hamstring strains.
Calves: Propel you forward and absorb impact. Strong calves improve running economy and ankle stability.
Hip Flexors: Lift your knees efficiently and maintain stride length. Tight or weak hip flexors limit running efficiency.

Core Muscles

The core stabilises your body during running and prevents energy leaks.

Abdominals: Support posture and reduce side to side movement.
Obliques: Help with rotational stability, particularly on trails or uneven terrain.
Lower Back: Keeps your spine aligned and reduces fatigue in long runs.

A strong core ensures your legs work efficiently and helps prevent injuries caused by poor posture or overcompensation.

Upper Body Muscles

While they are not the main drivers, the upper body contributes to balance, momentum, and form.

Shoulders and Arms: Aid with arm swing, balance, and rhythm. Strong arms prevent shoulder and neck tension.
Chest and Upper Back: Support arm movement and stabilise posture.

How Strength and Conditioning Improves Running Performance

Runners who include strength and conditioning in their training improve their running economy, endurance, and speed. Here is how it works:

Improved Running Economy

Running economy refers to how efficiently your body uses energy while running. Stronger muscles require less effort to generate the same stride, reducing energy wastage. Exercises like squats, lunges, and step ups build leg strength and contribute to a more efficient stride.

Enhanced Endurance and Power

Strengthening the lower body improves the ability to maintain force production over long distances. Hills feel easier, you maintain pace for longer, and your strides remain consistent even as fatigue sets in.

Reduced Injury Risk

Runners are prone to repetitive stress injuries. Strength work strengthens muscles, ligaments, and tendons, reducing the strain on joints. Core and glute exercises are particularly effective at preventing knee pain, IT band issues, and lower back discomfort.

Better Sprinting and Hill Running

Powerful muscles generate more force when running faster or tackling hills. Plyometric exercises such as box jumps or skipping improve explosive power and stride speed.

Strength and Conditioning Exercises for Runners

Not all strength training is the same. The best exercises focus on functional movements that mimic the demands of running.

Bodyweight Exercises

These are easy to do at home or anywhere, and are especially useful for beginners.

Squats
Lunges (forward, backward, walking)
Step ups
Glute bridges
Planks (front and side)
Push ups

Weighted Exercises

Adding resistance increases muscle strength and power.

Barbell or dumbbell squats
Deadlifts
Weighted lunges
Romanian deadlifts
Kettlebell swings

Start with light weights and focus on perfect form. Gradually increase load as strength improves.

Core Exercises

Strong core muscles reduce fatigue and help maintain posture.

Planks and side planks
Russian twists
Leg raises
Bird dogs
Stability ball exercises

Short, controlled repetitions are more effective than high volume movements.

Plyometric Exercises

Plyometrics improve power, speed, and running efficiency.

Box jumps
Skipping rope
Jump lunges
Broad jumps

These exercises teach your muscles to produce force quickly, improving sprinting, hill running, and stride turnover.

Mobility and Flexibility Work

Running can tighten muscles, so mobility work is essential for preventing injury and improving stride efficiency.

Hip flexor stretches
Hamstring stretches
Calf stretches
Foam rolling
Yoga or Pilates

Mobility exercises complement strength work, allowing muscles to function optimally.

How to Structure Strength and Conditioning Training for Runners

Integrating strength training into your running schedule requires balance to avoid fatigue and overtraining.

Beginners

1-2 sessions per week
Focus on bodyweight and core exercises
Sessions last 30-40 minutes

Intermediate

2-3 sessions per week
Incorporate weights and plyometrics
45-60 minutes per session
Schedule on easy running or cross training days

Advanced

3 sessions per week
Combine weights, plyometrics, and core work
Include mobility and flexibility work
Avoid heavy sessions before long runs or races

The key is consistency and progressive overload. Gradually increase weights, repetitions, or complexity to continue improving.

Strength and Conditioning Tips for Runners

Prioritise Form - Correct technique prevents injuries and ensures muscles are targeted effectively.
Warm Up Properly - Dynamic movements before strength sessions improve performance and reduce injury risk.
Focus on Weak Areas - Many runners have weak glutes or tight hip flexors. Targeting these areas will have a big impact on performance and injury prevention.
Complement, Don’t Replace Running - Strength work should enhance running, not replace it. The majority of training should still focus on mileage, intervals, and tempo runs.
Recovery Matters - Strength sessions place stress on muscles and connective tissues. Proper rest, nutrition, and hydration are essential to gain the benefits and prevent overtraining.

Nutrition and Recovery for Strength and Conditioning

Fueling properly is just as important as the exercises themselves. Muscles need protein to repair and grow, carbohydrates to fuel workouts, and fats to support overall health.

Some key tips:

Consume a protein source within 30-60 minutes post strength session
Hydrate before, during, and after workouts
Include carbohydrates to replenish energy if the session was intense
Consider collagen or targeted recovery supplements for joints and tendons

High quality natural energy gels and post run recovery shakes can be useful tools for runners who combine long runs with strength sessions.

Strength and conditioning is a vital part of a balanced running programme. Whether your goal is to run faster, further, or simply enjoy running without injury, dedicated strength work will support all of these goals. It strengthens the muscles you use when running, improves efficiency, reduces injury risk, and ensures your body is prepared for the repetitive stress of long distance running.

The most effective approach is consistent, well structured, and tailored to your running goals. Start small with bodyweight exercises, gradually add weights and plyometrics, and combine this with core work and mobility exercises. Pair this with smart running, recovery, and nutrition strategies, and your running will become more enjoyable, your pace more consistent, and your endurance more reliable.

Strength and conditioning is not optional for serious runners. By building a strong foundation off the road, every step you take on it becomes more powerful, efficient, and sustainable.
