This strength-building staple is one of the most potent ways to improve strength, power and athleticism. But reaping all the benefits relies on solid deadlift technique – and there are some common mistakes to avoid.
Read on and you’ll discover:
The deadlift is one of three fundamental resistance training exercises, alongside the squat and bench press. Deadlifts are a functional strength movement, engaging a lot of large muscle groups and training your body in a way that aligns with day-to-day activities – in this case building the strength to safely lift things from the floor.
During the deadlift you build integrated back and leg strength by working all the muscles of the posterior chain in unison. This means that all the muscles down the back of your body are engaged; the hamstrings, gluteus maximus, the erector spinae in the lower back, the scapula retractors and extensors in the middle and upper back; and the big latissimus dorsi muscles. You also build core strength and improve posture by engaging the abdominals.
While there are different ways to deadlift (you can start standing upright and lower the bar to your knees, start with the bar on a rack and lift it up until you are standing upright, or even start with the bar on the ground), they all involve working all of the muscles of the posterior chain in unison. That means there’s hamstring involvement, the glutes are engaged, and you’re working the lower back muscles and the thoracic extensors too.
This power-packed exercise is great for strengthening all the muscles down the back of your body, building core strength and improving posture. It can also work wonders for athleticism, as building strong posterior muscles is key to helping you move faster during explosive movements. Like any strength training, deadlifts can also contribute to improved bone health and improved heart health, and they can help you to sleep better and live longer.

As you lower the bar you should feel a stretch in the back of your thighs, and as you rise tall you should feel tension in the back of your thighs and your glutes. Throughout the movement, you should feel constant postural control through all regions of the back.
Most of the time your thoracic spine, which is the upper and middle area of your back, is naturally flexed, so to get the best results from your deadlifts you really need to focus on activating the thoracic extensors and scapula retractors (rhomboids and mid trapezius).
The easiest way to ensure you engage this important part of the posterior chain is to turn your elbows to the rear and keep them there as you complete your deadlifts.
You’ll notice that as soon as you turn your elbows to the rear, you get a little chest lift. This brings your shoulder blades back in towards your spine, you contract your scapular retractor muscles, and the muscles of your thoracic spine come into play. If you hold that activation as you complete the deadlift, you activate all the muscles that extend and stabilize your thoracic spine – and it makes your deadlift much more effective.
The key component of a deadlift is the hip hinge action. Practicing this without weight helps to improve trunk stability and isolate movement to the hip joint.
Simply stand side on to a mirror, knees bent, arms crossed in front of the chest – lift the chest to activate the extensors and tip forward ensuring there is no give occurring in the spine and all the movement is isolated to the hip. Remember to keep your chin tucked as your trunk inclines forward.
You can improve your deadlift performance by learning how to effectively breathe through the movement. Maximizing the benefits of deadlifts also relies on constant challenge and that means progressively increasing the weight you lift. This checklist provides guidelines on when to increase your load.
If you’re keen to practice your deadlift technique, you’re sure to get a good dose of deadlifts in any BODYPUMP or LES MILLS GRIT Strength workout. You can find a class or work out at home with LES MILLS+.
