one cannot have all the strength in the world, BUT if one lacks the skill and timing to use it efficiently and safely, then more strength or other fitness training will never solve any problems of speed!
Don't even think of trying to throw faster until you have reached a high level of accurate, well controlled skill (mechanics).
DON'T FULL YOURSELF! For Efficient Mechanics, not strenth, is the key to arm speed!
Just remember this, If you can not control and time the kinetic chain then all the weight training in the world will never get you arm speed!
