Core Training for Running: Which Exercises Are Most Effective

“Core strength is important” is advice every runner has heard, but most people don’t understand why, or which exercises to do. This article explains the specific role the core plays in running and provides a list of the most effective core training exercises.

1. Why the Core Matters for Running

The “core” isn’t just the six-pack abs—it’s an integrated muscle system covering the abdomen, back, glutes, and pelvic floor. During running, the core plays the following roles:

1. Stabilizing the pelvis: Prevents excessive pelvic sway with each foot strike
2. Transferring force: Transmits upper-body power through the core to the lower limbs
3. Maintaining posture: Prevents excessive forward lean or hunching in the later stages of a long run
4. Protecting the spine: Absorbs impact forces from landing

Research shows that core training can improve running economy by 3 to 5%, equivalent to running 8 to 12 minutes faster in a full marathon.

2. 7 Core Exercises Every Runner Should Do

Exercise 1: Plank

Target muscles: Transversus abdominis, quadratus lumborum, glutes

Proper form:

1. Rest on your forearms, elbows directly under your shoulders
2. Keep your body in a straight line from head to heels
3. Brace your abs—don’t let your hips sag or pike up
4. Breathe normally, don’t hold your breath

Recommended volume: 3 sets × 30 to 60 seconds

Running connection: Mimics the isometric contraction needed for core stability while running

Exercise 2: Side Plank

Target muscles: Obliques, gluteus medius (the muscle runners most need to strengthen)

Proper form:

1. Lie on your side, resting on your forearm
2. Lift your hips so your body forms a straight line from head to feet
3. Place your top hand on your hip or extend it toward the ceiling
4. Keep your pelvis from rotating

Recommended volume: 3 sets × 20 to 45 seconds (each side)

Why it matters: Weak gluteus medius is a common cause of runner’s knee and IT band issues

---

Exercise 3: Glute Bridge

Target muscles: Gluteus maximus, hamstrings, core stabilizers

Proper form:

1. Lie on your back, knees bent at 90 degrees, feet flat on the floor
2. Brace your abs and push your hips up until your body forms a straight line
3. Hold at the top for 2 seconds, feeling your glutes contract
4. Lower slowly (about 3 seconds)

Advanced version: Single-leg glute bridge (one leg lifted)

Recommended volume: 3 sets × 15 to 20 reps

---

Exercise 4: Dead Bug

Target muscles: Transversus abdominis, multifidus (deep core stabilizers)

Proper form:

1. Lie on your back, arms extended toward the ceiling, legs lifted with knees bent at 90 degrees
2. Keep your lower back pressed into the floor (don’t arch)
3. Slowly extend your right arm while simultaneously straightening your left leg (without touching the floor)
4. Return to the starting position, then switch sides

Recommended volume: 3 sets × 10 reps (each side)

Key tip: Your lower back must stay pressed to the floor throughout the entire movement

---

Exercise 5: Bird Dog

Target muscles: Multifidus, gluteus maximus, shoulder stabilizers

Proper form:

1. Start on all fours, wrists under shoulders, knees under hips
2. Brace your abs and keep your spine neutral
3. Slowly extend your right arm while reaching your left leg back
4. Hold at the top for 2 to 3 seconds
5. Return to the starting position, then switch sides

Recommended volume: 3 sets × 10 reps (each side)

---

Exercise 6: Russian Twist

Target muscles: Obliques, core rotators

Proper form:

1. Sit with knees bent, leaning your torso back about 45 degrees
2. Clasp your hands together or hold a weight
3. Rotate your torso, bringing your hands toward the floor (or extending to the side)
4. Return to center, then switch sides

Recommended volume: 3 sets × 20 reps (10 each side)

---

Exercise 7: Mountain Climber

Target muscles: Full-core engagement + cardiovascular conditioning

Proper form:

1. Start in a push-up position, hands on the floor
2. Brace your abs and keep your body in a straight line
3. Alternately drive your knees toward your chest at a fast pace
4. Maintain speed without letting your hips bounce

Recommended volume: 3 sets × 30 to 45 seconds

3. Core Training Program Structure

3 Core Sessions Per Week

Time per session: 15 to 20 minutes

Suggested structure:

Phase	Exercise	Time/Sets
Activation	Glute Bridge + Dead Bug	2 sets each
Main	Plank + Side Plank + Bird Dog	3 sets each
Strengthening	Russian Twist + Mountain Climber	2 sets each

When to Do It

• After running: Ideal (muscles are already warmed up)
• Before running: Light activation moves (glute bridge, bird dog); high-intensity core work is not suitable
• Rest days: Full core session can be done

4. Special Recommendations for Runners

Muscle Groups Runners Most Often Neglect

Muscle Group	Importance	Recommended Training
Gluteus medius	Prevents runner’s knee	Side plank, lateral band walks
Deep transversus abdominis	Pelvic stability	Plank, dead bug
Hamstrings	Prevents hamstring injuries	Single-leg glute bridge, Nordic hamstring curl
Gluteus maximus	Source of propulsion	Glute bridge, Romanian deadlift

5. When You’ll See Results

Timeframe	Expected Results
2-4 weeks	Improved pelvic stability while running, reduced side-to-side sway
6-8 weeks	Noticeably better posture maintenance in the later stages of long runs
3 months	Overall running economy improves, slight speed gains

Conclusion

Core training doesn’t require a huge time commitment. With systematic training of just 3 sessions per week, 15 minutes each, you’ll see clear improvements in your running form and efficiency within 3 months. Incorporating core work into your regular running routine is one of the most cost-effective investments you can make in your running.
