Alongside your sprints, having a decent pair of running trainers, interval training and strength work, your core is also key if you want to improve your running speed. Why? Because a strong core leads to improved posture and stabilisation of your torso, which helps you move more efficiently and maximise your power. You don’t have to spend hours working on your midsection either, this 10 minute routine is perfect for slotting into your training a few times a week, and it requires no equipment.
But it’s not just speed that boosting your core strength can benefit, it can also reduce the likelihood of injuries and improve your running economy (the amount of oxygen your body needs to run at a certain pace). A 2019 study that looked at two groups of college athletes found that those who added three core workouts into their training, over an 8 week period, saw improvements in balance, core endurance, and running economy. While the group that carried on with their regular training and didn't add in any core exercises saw no improvements.
