The simple fact is that compuond lifts coupeled with a solid diet will result in greater mass ( and strength) gains than isolation lifts. As everyone else has said- stick with presses, deads, squats, OHP's, dips and the sort until you have achieved a solid foundation. Most natural athletes will not benefit from high volume, single body part splits and / or loads of isolation exercises.
Want Proof? I refer you to many of the guys and gals on this forum as well as big names such as - Reg Park, Arnold, (who followed Park's methods to get big and strong) Franco Columbo ,Bertelli Fox,Mark Rippetoe, John MaCallum, Randall Strossen and the list goes on and on.
But please remember you gotta lift big, eat big and sleep big to get big.... do not alter the formula and you will do fine. oh yeah, and bacon!!! Goood luck and happy lifting.
The only rep that counts is the next one.
