Hi everyone-- just started NROLFW. I'm wondering-- is it better to go with a high step/lower weight with the step-ups or go with a lower step, higher weight?
I used a high step this morning with two 15 pound dumbbells-- and it about killed me.

(In a good way). Should I stick with the high step and the lighter dumbbells, or should I go for the medium step and increase the weight?
any thoughts?
