Actually, testosterone (and thus steroid testosterone derivatives) have been shown to directly accelerate motor learning. Before puberty boys and girls learn motor skills at roughly the same rate, but once in puberty boys learn motor skills significantly faster than girls (even ones that are unathletic like finger tapping). In addition to all their other benefits steroids cause you to get more out of each training session.
