From what little I’ve read, the “off” foot should be set onto something to reduce the shear forces on the knee if it becomes an issue. Personally, my minimal experience doing hip dominant movements with my off foot elevated leads me to believe it’s inevitably going to cause problems, and that you should only do them with your other foot anchored onto something. I don’t know how that effects activation though.

My thing with unilaterals that involve holding something in your hands is that each set takes twice as long as a bilateral one – and this is because I don’t have straps. Because of this, I don’t do single leg RDLs (tried them out a few times), and can’t speak from experience on how they should be done and what to watch out for.

Hip thrusts – I like them, but they allow for a lot of weight to be moved (even the unilateral variant), and I kind of have setup issues when using appropriate weight. Regardless, I agree that a lot more hip work is needed than most people recognize. 🙂

I remember seeing Rod Laver, the great Aussie tennis player, and his left arm looked like Popeye’s, lol!
