Mark Ottobre shows how deep to go on an RDL using a "superglue" cue: one hand on your head, one at the base of your spine to keep your torso rigid. Stop when the hand at your back lifts off, because going lower rounds your spine.

So when Jake hinges here, we can see there's a few things going on. It's not perfect, a little bit of bending from the spine. Come back up. All you need to learn this is a stick. Now the instruction I'm going to give is we're going to put one hand at the top, we're going to put your other hand at the bottom, and we're going to superglue your hand to your head and your hand to the bottom of your spine, and we're going to do the hinge. Now I want you to go as low as you possibly can, but the rule is this has to be superglued. So start and superglue both of those in. And let's move from the hips, pushing the hips back. We're going to find Jake's end range pretty quickly when we do this. So you can see here immediately his hand has come off his back. Come back up, Jake. So for him to maintain that arc in his back, that is his end range. Go again for me. So starting him off in a stiff-legged deadlift or an RDL, this is where I would put Jake in this position. I wouldn't get him to go any lower than that. Asking that of Jake at this point, he's going to need to round his back. If you enjoyed this tip, make sure you follow my page, Mark Ottobre, for more.
