Technical notes about rotisserie hip thrusts:

Because your back is supported, I don’t think we’ve ever experienced a back injury from them a Glute Lab. In fact, people who experience back pain with normal hip thrusts choose rotisserie as they can always do them pain free.

They’re unlike normal hip thrusts in that they’re actually heavier and harder at the bottom and lighter at the top. This is due to the counterbalancing of the upper body over the fulcrum. This is what makes them so unique.

This is why people tend to lift around 30% heavier weight with rotisserie hip thrusts than normal hip thrusts. They max out bottom range load by making the lockout easier, shifting the resistance profile.

For these reasons, they’re not a true hip thrust IMO. A hip thrust is hardest at the lockout. We even purposely make hip thrusts harder at the top by adding pauses, pulses, and bands added to the bar.

I do love rotisserie for being harder at the bottom (and for being easy on the back) because this (and squats and lunge movements) strengthen your hip thrust out of the hole.

Then we do barbell hip thrusts and the pauses, pulses, and bar plus band (along with the kneeling glute isolator machine with pure band resistance), and we end up with a much stronger hip thrust (by maximizing stretch and squeeze portion strength).

Which should translate to bigger glutes.

Now, this woman’s form looks off for two reasons:

1) She’s unstable. This vastly improves within a couple of weeks.

2) She’s hyperextending her spine. Which is normally risky. But with the back support, it’s not that risky. But it is unsightly. So I just tell people who do that to look forward and keep ribs down and it instantly solves that.

The last thing I want to say is that rotisserie are unique to the original Bosu ball inside a trap bar concept (and also to the Nautilus Glute Drive, which rotates similarly) as the fulcrum is up high, so you don’t get the counterbalancing (which shifts the resistance profile).

With rotisserie, at the lockout, the bar ends up closer to the fulcrum, and prob 40% of your bodyweight ends up behind the fulcrum. So it’s probably 50% heavier at the bottom compared to the top.
