What are the biggest mistakes you made, and that you see beginners make when they are trying to build muscle?
Notes to participants:
1) Participants should ignoring how others respond and not just chime in with "what he said", if this makes sense. This doesn't mean answers have to be long. I would just prefer them to be independent of what others are saying.
2) Answers can be as long or short as you desire. I want this e-book to be organic and not something that becomes a burden for those responding.
