From a lateral flexion perspective, this is your side planks, your hip dips.

Some people do these on a physio ball or a Swiss ball, and you can do like a side crunch, or some people call these oblique V-ups or oblique sit-ups.

And you can just kind of imagine this lateral flexion.

The anti-version is probably a little bit easier to understand than the anti-flexion.

Anti-lateral flexion are holding that thing from moving sideways.

So this is a side plank with a row.

So imagine being in a side plank position and then you're actually with a cable and you're rowing it to yourself.

You could simply do a lateral plank as well.

You could do a suspended lateral plank.

And so in that particular case, imagine you're on your side and your feet are in a TRX band.

And let's just say you're on your right shoulder, your right elbow's on the ground.

What's happening is you're not actively flexing, but you're stopping your side from dipping and hitting the ground.

So you're avoiding unwanted lateral movement.

That's the anti version here.

If it's easier for you to think about anti-core exercises as simply eccentric or avoiding eccentric movement, that's fine too, right?

But you're not actively moving, you're avoiding movement in this case.

You could also think of them as like slight plays on isometric exercises, similar thing.

If none of that made sense, don't worry about it.

Just keep thinking of the anti-movement.

So that's flexion and lateral flexion.
