Low Poly Femur

Hello everyone!
Since this forum helped me immensly with my last problem I thought I’d come back here with another problem.

I’ve got a femur bone and I want to follow this tutorial: Spherene Femur Tutorial

Now the person in the tutorial says, that he made a low poly version of the femur bone and I can’t find any video or information on how I can make that with my bone the way he does it in his video.

I try to add my STL if it isn’t too big.

I hope that somebody here can help me with my problem.

Thank you in advance!

Edit: I tried using ReduceMesh but it did not look the slightest bit like in the video.

not sure what you are aiming for, something like this perhaps? Make sure to uncheck adaptive count:

Thank you for your answer and your help!
I think that’s the way to go.
