Strength Training for Runners: A Complete Program of Squats, Lunges, and Single-Leg Exercises

“Do runners need to do strength training?” The answer is unequivocally—yes. A large body of research confirms that systematic strength training can improve running economy by 2-8%, reduce injury risk by more than 50%, and enhance sprinting ability and long-distance endurance. However, strength training for runners is vastly different from bodybuilding-style training. This article provides a complete periodized program designed specifically for runners.

The Science Behind Strength Training for Runners

Why Can Strength Training Make You Run Faster?

1. Improved running economy: Stronger muscles use a lower percentage of their maximal force with every step, reducing oxygen consumption (Støren et al., 2008)
2. Enhanced tendon elasticity: Increased tendon stiffness from resistance training allows for greater storage and release of elastic energy
3. Delayed fatigue: Stronger muscles can better maintain running form over long distances, reducing compensatory movements
4. Injury prevention: Strengthening the muscle groups that support the joints, particularly the glutes, quadriceps, and calf muscles

Won’t I Get Bulky?

This is the most common concern among runners. Research clearly shows that when endurance training is performed concurrently, the hypertrophic effect is significantly suppressed (the “interference effect”). What runners gain from strength training is primarily neuromuscular efficiency, not muscle size. As long as you don’t deliberately overeat or drastically reduce your running volume, the likelihood of gaining weight is extremely low.

Periodized Training Structure

Runners’ strength training should be synchronized with the phases of their running program:

Phase	Duration	Focus	Sets × Reps	Load	Frequency
Adaptation	3-4 weeks	Learn movements, build foundation	2-3 × 12-15	Light (RPE 5-6)	2-3 times per week
Maximal Strength	6-8 weeks	Build maximal strength	3-4 × 4-6	Heavy (RPE 8-9)	2 times per week
Power Conversion	4 weeks	Convert strength to speed	3 × 5-8	Moderate (RPE 7, explosive tempo)	2 times per week
In-Season Maintenance	Depends on season	Maintain strength levels	2-3 × 6-8	Moderate-heavy (RPE 7-8)	1 time per week

Detailed Breakdown of Core Exercises

Exercise 1: Back Squat

Why should runners squat? The squat trains the quadriceps, gluteus maximus, and core stability—these are the primary muscle groups involved in running push-off and impact absorption.

Technical points:

• Feet slightly wider than shoulder-width, toes pointed slightly outward (15-30 degrees)
• Descend until thighs are parallel to the ground or slightly below
• Knees track in line with toes, avoid caving inward
• Keep the back neutral and core braced
• Heels remain in contact with the ground throughout

Runner’s variation: The Front Squat places greater demands on the core and more closely mimics the upright posture of running.

Exercise 2: Lunge Series

Lunges are the strength exercise closest to the running movement pattern—single-leg support, dynamic balance, and force production in the anterior-posterior direction.

Forward Lunge:

• Step forward, front knee should not travel too far past the toes
• Lower the back knee until it lightly touches or nearly touches the ground
• Push off with the front foot to return to the starting position

Reverse Lunge:

• Step backward, which is more knee-friendly
• Suitable for runners with knee issues

Walking Lunge:

• Perform consecutive forward lunges to mimic the continuous action of running
• Can hold dumbbells to increase the load

Exercise 3: Bulgarian Split Squat

A must-do exercise for runners! This single-leg exercise forces each leg to work independently, helping to identify and correct strength imbalances between the left and right legs.

Technical points:

• Place the rear foot on a chair or step approximately knee height
• Position the front foot about 60-90 cm from the chair
• Lower until the front thigh is parallel to the ground
• Keep the torso upright, avoiding excessive forward lean

Exercise 4: Romanian Deadlift

Trains the entire posterior chain—glutes, hamstrings, and lower back. These muscle groups are responsible for hip extension and impact absorption during running.

Technical points:

• Feet shoulder-width apart, knees slightly bent
• Hinge at the hips to lean forward (Hip Hinge)
• Slide the barbell or dumbbells down along the front of the thighs
• Feel the stretch in the hamstrings to its limit, then return to standing
• Keep the back neutral throughout

Single-Leg Version (Single-Leg RDL): An advanced variation that adds a balance demand, more closely replicating the single-leg support situation of running.

Exercise 5: Calf Raises

The calf muscles and Achilles tendon endure tremendous loads during running. Strong calves are key to preventing Achilles tendinitis and plantar fasciitis.

Straight-Leg Calf Raise: Primarily targets the gastrocnemius

• Stand on the edge of a step with heels hanging off
• Raise up slowly (2 seconds) → pause at the top for 1 second → lower slowly (3 seconds)
• 3 × 15-20

Bent-Knee Calf Raise: Primarily targets the soleus

• Seated position, knees bent at 90 degrees
• Use the same raise/lower tempo
• 3 × 15-20

Scheduling Strength Training and Running

Principles for Doing Strength and Running on the Same Day

Run First, Then Strength (Recommended):

• Suitable for quality running days (intervals, tempo runs)
• Running performance is not compromised
• Strength training in a slightly fatigued state is also acceptable

Strength First, Then Run (Occasionally):

• Suitable for easy run days
• Running pace will be affected, but it helps adapt to running under fatigue

Optimal Schedule (4 runs + 2 strength sessions per week):

Day	Morning	Afternoon
Monday	Easy run 40 min	Strength A
Tuesday	Interval training	—
Wednesday	Rest	—
Thursday	Easy run 40 min	Strength B
Friday	Rest or easy run 30 min	—
Saturday	Long run	—
Sunday	Complete rest	—

Gym Recommendations for Runners in Taiwan

Taiwan offers a wide variety of gym options. Here are some suggestions:

• Large chain gyms (World Gym, Fitness Factory): Full equipment, suitable for executing complete training programs
• Dedicated free-weight gyms: Suitable for advanced trainees, usually with a more focused atmosphere
• Home training alternatives: If you can’t get to a gym, a set of adjustable dumbbells (5-30kg) plus a chair can complete 80% of the exercises

Frequently Asked Questions

Q: How long before a major race should I stop strength training?

Do your final strength training session 7-10 days before the race, maintaining intensity but halving the volume. Research shows that stopping completely for more than 2 weeks begins to cause strength loss.

Q: My legs are very sore after strength training, which affects my run the next day. What should I do?

You will experience noticeable DOMS during the first 2-3 weeks of the adaptation period, which will significantly decrease afterward. Schedule strength training before easy run days or rest days.

Q: Should female runners also lift heavy weights?

Absolutely. Women’s testosterone levels are far lower than men’s, making it much harder to increase muscle size. Research shows that female runners gain similar improvements in running economy from strength training as men do.

Conclusion

Strength training is not an “add-on” to running—it is a core component of a complete training plan. Investing 60-90 minutes per week in strength training yields faster paces, fewer injuries, and a longer athletic career. Make your body not just an engine, but a high-performance running machine with a solid chassis and efficient power transfer.
