To get the most out of the exercise it’s crucial that your form is perfect. So try and avoid these common mistakes.

Keep your hips level

“It’s important to keep your hips level and your weight distributed evenly,” explains Williams. “Make sure to engage your core to keep your spine neutral and only go so far as your strength and mobility allow. For example, if you’re performing the movement on your left leg, don’t let that hip tilt and stack over your right hip.”

Avoid lifting your head

“Lifting the head too high will cause a curve in your spine,” says Jackson. “You are looking to keep your spine neutral so focus on looking between your fingertips.”

Don’t rush

“One of the things we see most commonly as personal trainers is people rushing through the movements, or trying to get it over with as soon as possible,” says Allsobrook. “You only do yourself a disservice by doing so, losing out on the impact a slower, more controlled movement can have. Take it slowly, making the most of each rep, and keep those movements under your control.”

Aim for a 45-degree angle

“You should aim for that 45 degree angle with your leg,” adds Allsobrook. “Not everyone can do that, and that’s perfectly fine, but it should remain your target, as you’ll get closer and closer each time you do this exercise. I’ve seen clients be overkeen with this, and take it too far, which risks a loss of balance, as well as a strain or overstretch.”
