In reply to broccoligirl:
Don't confuse strength with power. Campus boarding is a normally a power thing ie. generating force explosively via 'plyometrics' (using the recoil at the bottom of the movement to bounce back up). Strength is better gained from deadhangs, pull ups, lockoffs etc.
However, I must say, all the women I've seen outdoors seem to always do everything slow and 'statically'. I once showed one girl a problem using a double slap/recoil and she instinctively did it as a static rockover. Faultless clean technique, but a totally different way of approaching movement over rock.
To summarise, dynamic, slappy moves can be trained anywhere. If you want to specifically train 1-5-9, get on a campus board.
