Can you define thin, hard and wiry in a way that actually means something? Like, something that would be used by a biologist, doctor or sports coach?
Sprint distance will have completely different effects on body composition to endurance distances in both sports. It's highly misleading just to refer to them as just cycling and running.
No such thing.
Who, the powerlifters or the Olympic lifters? Actually, neither train like this.
Your conclusion is correct but is not connected at all to your premises. I know it sounds like I'm just *****ing about semantics but it's clear you don't understand exercise physiology or at least how to properly explain what you may have come to understand in your own training. Posting stuff like you did makes it harder for beginners to understand, not easier.
