Runners should be able to control a single leg squat down to chair level and rise back up again, but I am always surprised by the number of runners I see in our physio clinic who don’t have the strength or balance to do one.

Watch this video to learn the technique and then test yourself.

If you can’t control a proper single leg squat, then start practising. 10 reps each side every day. It will cost you 2 minutes, but reap you a lot of rewards in terms of your running strength and speed.
