You can learn alot more from a 150' thrower than a 200'er. Emulate those who get the most from their ability, not necessarily those with the most ability. When faced with major technique problems, revert back to the basics. Rely on fundamentals and drills to get you through. Don't take 60 throws when you feel yourself tiring after 40.
Muscle fatigue leads to overcompensation and in turn technique breakdown.
Thou shalt not follow bodybuilding magazine workouts. You're not a bodybuilder and you don't juice like the IFBB stars. Less is often more. This is especially true as you get older. One set to failure for each bodypart every four to seven days can give better results than every other day marathon sessions.
