Unilateral training should be a non-negotiable in everyone’s training. It translates well into athletics and everyday living. The single-leg Romanian deadlift is one of the best exercises to train the posterior chain.

The hardest part about the single leg RDL is balance and hip control - especially if you don’t usually train this movement.

One common movement fault with the single leg RDL is the outward rotation of the hip. When the pelvis rotates out (and you can see it because the foot/toes likely also point out), we lose the tension needed in the hamstrings and glutes to reap the benefits of this movement.

A simple way to improve this is to use a foam roller for external feedback - it guides the foot as the hip goes into extension and makes sure the leg follows the path throughout the movement.

Hope this helps!
