If you’re training for a marathon or half marathon, you don’t have time for injury – that means you need to protect against it from the very start. Jason Fitzgerald, founder of online coaching service Strength Running, has created this workout to do just that.

These moves work your abs as well as your hips, glutes, lower back and hamstrings – all the muscles that help you maintain proper running form even when you’re fatigued. ‘I always seem to get hurt when I get lazy and stop doing this routine consistently,’ says Fitzgerald. Do each exercise for 45 seconds. Go through all the moves twice; it will take about nine minutes. After a few weeks, increase to one minute for each exercise.

Start on all fours, with a flat back. Lift your left arm so it’s parallel to the ground. At the same time, lift your right leg so your thigh is parallel to the ground and your shin is perpendicular. Your knee should be bent at 90 degrees and your glutes should be activated. Hold for several seconds, then switch sides. Continue alternating.

Lie on your left side, then lift your body so your weight is on your left forearm and the side of your left foot, forming a diagonal line from head to feet. Hold. To make it harder, add a lateral leg raise: lift your right leg about 45 degrees, hold for a few seconds, then lower. Repeat five to 10 times. For the second set, switch to your right side.

Lie on your back, legs extended. Raise your left leg and bend it 90 degrees. Raise your right leg two to three inches off the floor. Hold for several seconds, then switch. Continue alternating.
