10 minutes of strength a day for runners

Ask a group of runners what they would change about their training and most will say "more strength work". Ask what they actually did last week and the honest answer is usually nothing. Not because they do not believe in it, but because a 45-minute gym session is one more thing that does not fit.

So drop the gym session. Ten minutes a day, done at home, adds up to more than an hour of strength work a week, and a daily habit is far easier to keep than a weekly appointment.

Why runners need strength at all
Running is not a cardio activity with some leg movement attached. Every stride is a single-leg hop that lands with two to three times your body weight, repeated around 160 to 180 times a minute. Your calves, hips, glutes and trunk are what absorb and return that force. When they are strong, each stride costs less energy, your form holds together late in a run, and your body copes better with the weekly mileage. When they are not, the same mileage feels harder than it should.

The 10-minute routine
Two exercises for the calves and feet, two for the hips and glutes, one for the trunk. Move slowly, two seconds down and one second up, and rest only as long as it takes to switch sides.

• Single-leg calf raises, 3 sets of 12 per side. Stand on a step, lower the heel below the edge, rise all the way onto the toes. Hold a wall for balance, not for help.
• Split squats, 3 sets of 10 per side. One foot forward, one back, lower the back knee towards the floor and keep the front heel down.
• Single-leg glute bridges, 3 sets of 12 per side. Lie on your back with one foot flat, drive the hips up until the body is a straight line from shoulder to knee.
• Side plank, 2 holds of 30 seconds per side. Hips high, top foot stacked on the bottom one or placed in front of it.
• Step-ups, 2 sets of 10 per side, on a stair or a sturdy box at knee height. Step up without pushing off the back foot, step down under control.

That is the whole thing. No equipment except a step, no changing clothes, no excuses.

How to fit it into the week
The simplest version is to do all five exercises every day. If that feels like too much for your legs, split them: calf raises and step-ups on Monday, Wednesday and Friday, bridges, split squats and side plank on Tuesday, Thursday and Saturday, and 10 minutes of relaxed mobility on Sunday.

Timing matters more than most people think. Do the routine straight after an easy run, when you are warm, or at a fixed point in your day such as before your morning shower. Avoid the evening before a key session or a race, because fresh strength work leaves a little soreness behind and you want those days to feel good.

How to progress it
A routine that never changes stops working after a few weeks. Make one small change every two weeks, in this order: add two repetitions per set, then slow the lowering phase to three seconds, then add load, a backpack with a few books in it or a single dumbbell held at the chest. After six to eight weeks of this, you can swap the step-ups for 20 to 30 small two-footed hops on the spot, landing softly and quietly, which teaches the calves and tendons to spring rather than just hold.

Keep a note of what you did. "Three sets of twelve with the blue backpack" is a number you can beat next time; "some calf raises" is not.

The mistakes that undo it
Doing a week of enthusiastic sets and then nothing for a month. Starting with weights before the bodyweight version is clean. Holding your breath on every repetition. Skipping the single-leg work because the two-legged version feels more impressive. And the most common one of all: dropping the routine the moment a race approaches, which is exactly when a body that is used to it benefits most.

Pick one exercise from the list and do it today, after your run. Tomorrow add a second. By the end of the week you will have a routine, and by the end of the month it will simply be part of how you train.
