I sure what you guys are talking about is plyometric. I have always been under the impression that plyometrics have to be fast movements that emphasise explosiveness!

For instance doing 10 ordinary pressups and then moving straight into 10 clap pressups, this way you work the slow twitch muscle fibres with the 1st set and then you work the fast twitch muscle fibres with the second set of pressups. Just my thoughts!
