Fast and slow twitch are based on your muscle fibers, sure some people are born with more then others. However; you can train your body to be more explosive by doing the correct exercises, not sure why that's difficult to understand....
You can't change the % of fibers, you can train to optimize the fibers that you do have. There is a difference.
The ceiling for some is greater than for others. Trust me, I understand. Studied this for a long time.
