About that "leg jiggle"?
An instructor at my gym, who does both step and weight training, and has a BOD TO DIE FOR in terms of muscle definition, STILL has a slight jiggle in her legs.........so Im not sure how much we can rely on exercise to completly tone and harden the leg muscles so they dont jiggle.
Anyway, back to the point. Step for me, seems to only lean out my quads and a little glute, so I do have to incorperate "other" leg exercises in there.
I havent noticed in difference in my calfs at all.
