A physiotherapist says you only need 20 minutes and four movements to be a better runner

Strength training should be an important part of every runner's training plan. "Any runner who is serious about their running should be strength training regularly," says Richelle Weeks, a certified running coach and running physiotherapist at Sportscience Ottawa. "When done properly it can improve performance by 5% because it improves running economy. It can also help reduce common overuse running injuries. Especially in the 40-plus runner!"

Finding the time to strength train on top of running (you do also need to keep running to become a better runner) can be easier said than done, but Weeks has helpfully posted this (and other) 20-minute routines you can do at home. Weeks says the workout targets the "most important running muscles" including the calves, quads, the glutes, hamstrings and core.

If you have more time Weeks recommends adding upper-body exercises, too. "It can help maintain an upright posture when fatigued during a race, like at the end of a marathon. It can also help make arm swing efficient. Runners can just choose one push exercise—think push-ups, shoulder presses, bench presses—and one pull exercise—think pull-ups, inverted rows, bent-over rows, back fly."

How to do Richelle Weeks' 20-minute strength workout for runners

In case you're unfamiliar with the exercises in the video and need to check how to do them, the exercises Weeks has chosen are the side lunge, glute bridge march, side plank rotation and calf raise.

Weeks recommends aiming for three sets of eight reps. "If things start to feel easier, instead of doing more reps go heavier with your weights," Weeks writes in the caption. "Runners should be focused on low rep / high weight."

Intrigued, I asked why she recommends this rep range. "The best way to get strong is to lift heavy or use heavy resistance bands. It's hard to go heavy if you're doing many reps so it's ideal to start with three sets of 8-10 where you try to choose a resistance that makes the last rep challenging.

"You don't lift to failure but basically you want to have two reps left in you once you've done each set. More than that means you can go heavier. Eventually, you want to go towards three sets of six because that can allow you to lift even heavier."

You will need weights to do this workout and we recommend adjustable weights so you can use heavier weights as you get stronger. Here are three options to consider.
