Nonsense - Lamarck sounds good to me. One question - does any adaptation absolutely need to have happened before my birth. To put it another way, if I mither my parents into doing more training now, will I get better without training any harder?
Also, where does Zen come into it? Can I get faster by thinking about it more?
And another thing, if I've been reincarnated from having been a slow animal (like a hedgehog), should I work on my distance training more or focus on sprints?
