Step Ups for Glute-Quad Training: What height?

Hi,


If anyone has used or is using these in your training program, what height did you begin with? I know it will be different for each person, but I'm just curious. Also, did you choose to use a barbell or dumbbells?


Please help.

I didn't find the right solution from the Internet.
