Core Training for Runners

A strong core keeps you running tall and injury-free. These exercises take just 20-30 minutes and need zero equipment.

How to use:Your training plan shows "Core · 2 sets" or "Core · 1 set." One set means doing all of the exercises below in order, resting 30 seconds between exercises. Then rest 60 seconds before the next set.

Plank

Get into a push-up position but rest on your forearms instead of your hands. Keep your body in a straight line from head to heels. Hold steady — don't let your hips sag or pike up.

3 sets of 30-60 seconds

Why it matters: A strong core keeps your torso stable while running, so your legs don't waste energy compensating for a wobbly upper body.

Dead Bug

Lie on your back with arms pointing toward the ceiling and knees bent at 90 degrees. Slowly extend your right arm overhead while straightening your left leg. Return to start and repeat on the other side.

3 sets of 8 per side

Why it matters: Teaches your core to stay stable while your arms and legs move — exactly what happens when you run.

Bird Dog

Start on your hands and knees. Extend your right arm forward and left leg backward at the same time, keeping your back flat. Hold for 2 seconds, then switch sides.

3 sets of 8 per side

Why it matters: Builds the cross-body coordination that powers an efficient running stride.

Side Plank

Lie on your side with your forearm on the ground and feet stacked. Lift your hips off the floor so your body forms a straight line. Hold steady.

3 sets of 20-30 seconds per side

Why it matters: Strengthens the muscles that keep your hips level while running. Weak hip stability is a major cause of knee and IT band problems.

Bicycle Crunches

Lie on your back with hands behind your head. Bring your right elbow toward your left knee while extending your right leg. Alternate sides in a pedaling motion.

3 sets of 12 per side

Why it matters: Works the rotational muscles that help you maintain good posture in the later miles when fatigue sets in.
