Aches and pains in the lead-up to race day, followed by glute and lower back pain when I crossed the finish line.<\/p>\n
I learned the hard way that core work and strength training in general is essential for runners.<\/p>\n

So I resolved not to make the same mistake again and sought advice from Claire Mills, physiotherapist, Pilates instructor and founder of Core LDN<\/a>, who explained why developing a strong core is worth the investment of time and effort.<\/p>\n \u201cIt\u2019s about creating a stable foundation that allows the arms and legs to move efficiently while controlling the forces traveling through the body,\u201d Mills tells Fit&Well.<\/p>\n Every time your foot hits the ground when running, your body absorbs forces of around two to three times your body weight.<\/p>\n \u201cYour core muscles\u2014including the deep abdominal muscles, diaphragm, pelvic floor and muscles surrounding the spine\u2014work together to stabilize the trunk and pelvis so these forces are managed effectively,\u201d Mills explains.<\/p>\n \u201cA strong, well-coordinated core helps runners maintain efficient mechanics throughout a run, rather than just during the first few miles.\u201d<\/p>\n What to read next<\/p>\n A strong core could also reduce your risk of injury.<\/p>\n \u201cWhile no exercise program can completely prevent injuries, better lumbopelvic control may help reduce excessive movement that contributes to common running problems such as patellofemoral pain, iliotibial band syndrome, Achilles tendinopathy and lower back pain,\u201d Mills says.<\/p>\n As I\u2019m a runner who is guilty of skipping core work, I asked Mills to share her best core strengthening workout\u2014and there isn\u2019t a sit-up or regular plank hold in sight.<\/p>\n \u201cMy advice is to move away from thinking about endless sit-ups or planks held for several minutes,\u201d Mills says. \u201cThe goal is functional strength that transfers into running.\u201d<\/p>\n \u201cInclude exercises that challenge anti-rotation, anti-extension and lateral stability,\u201d she says.<\/p>\n As well as the right selection of exercise, they must be done consistently, and Mills recommends runners do 15 to 20 minutes of core strength training two to three times per week.<\/p>\n \u201cThe key is consistency rather than intensity,\u201d she says.<\/p>\n How to do the five-move core workout <\/p>\n Mills has created a workout that focuses on building core strength with five Pilates-inspired exercises\u2014so be sure sure to focus on your breath.<\/p>\n \u201cCoordinating your breathing with your deep abdominal muscles improves stability and control,\u201d Mills explains.<\/p>\n The five exercises are:<\/p>\n Dead bugModified side plank with leg liftBird dogSingle-leg glute bridgePallof press1. Dead bug<\/p>\n Sets: 2-3 Reps: 8-10 each side<\/p>\n How to do it:<\/p>\n Lie on your back and lift your legs so your hips and knees are bent to 90\u00b0.Reach both arms straight up.Gently draw your lower ribs down and maintain a neutral spine, engaging your core.Exhale as you slowly lower one arm behind you and lower and extend the opposite leg until both are just above the floor.Inhale as you reverse the movements back to the starting position.Repeat with the opposite arm and leg.Continue, alternating sides with each rep.<\/p>\n Benefits: Improves deep core control, builds trunk stability while moving the limbs and reduces excessive movement through the lower back during running.<\/p>\n 2. Modified side plank with leg lift<\/p>\n Kneeling Side Plank + Leg Lift – YouTube Watch On <\/a><\/p>\n Sets: 2-3 Reps: 8-10 each side<\/p>\n How to do it:<\/p>\n Lie on your side with your knees bent and legs together, propped up on your forearm, with your elbow directly under your shoulder.Exhale as you lift your hips until your body forms a straight line from your shoulder to knees.If you can, straighten the top leg and lift and lower it as you hold the side plank position.<\/p>\n Trainer tip: Keep your shoulders, hips and pelvis facing forward. Avoid letting your top hip rotate.<\/p>\n Benefits: Strengthens the oblique muscles and lateral hip stabilizers, improves pelvic control during single-leg stance and helps reduce excessive hip drop, which is common in runners.<\/p>\n 3.
