Its completely individual, everyone is different (body builders are all different). some guys 5 hours, some guys 10 . Tiger Woods only slept about 3 hours per night and was able to play golf at the highest level on that little of sleep
3 hours sleep per night, I call bullshit or amphetamines or bullshit
Then again, Tiger Woods is a stick hitting a put put ball with a stick so, no need for growth there and was clearly too busy fucking other chicks to care so
Lesson learned then. Sleep 3 hrs/night, tap lots of ass, play golf, profit. I need to try thatwell when he was only getting 3 hours of sleep a night cause he was too busy getting a piece of ass .. thats when he was the best golfer in the world . fucking going to 'sex addiction' counseling ruined his ass .. he started sleeping more, and stopped tapping ass , and then became a shitty golfer. go figure
Lesson learned then. Sleep 3 hrs/night, tap lots of ass, play golf, profit. I need to try that
OP there is no general answer to your Q's. As said we are al different and we also go through some personal sleep needs cycles.
Sometimes people take short naps during the day so it's a guess at best. UNLESS you tap into their world and do some survey for an average across the board with the pro's. Sleep requirements also change with age so with that how old is this newbie pro and how old is the vet pro?
