The rotational inertia of your leg is greater when your leg is

straight

bent

same either way

Inertia doesn't apply to living flesh, only dead matter. Having said that, sure hope you're not a zombie.

So I'm not misunderstood, living flesh always has force applied, whether in rotation or anti rotation. There is no complete relaxation, therefore no inertia. So, the answer is Same either way.

It would be bent, and your welcome
