Finding the motivation to run is one thing. But when it’s cold, rainy and dark outside, the last thing you want to do is get out for a plod around the block. Sometimes, you just have to force yourself to put on your trainers and reflective, wet-weather activewear to get those miles in.

But for those times when you just don’t fancy it, there are plenty of ways to improve your running without even lacing up your shoes. Especially when it comes to your core.

Whether you’re a long-distance runner, a sprinter or simply trying to get from the couch to 5k, developing full-body strength, good balance and stability are all important, and your core can deliver all of this.

“When it comes to running, a strong core is one of the main foundations,” says Imo Boddy, a personal trainer and founder of the online coaching service Lift and Run. “A strong core keeps you dynamic but stable and upright in the torso, which helps with power, efficiency, form and injury prevention,” Boddy tells Stylist.
