You cannot spend a third of a century around physical culturists and barbell men without coming to a few conclusions. You see many enthusiasts who thrive on their training schedules and attain a perfectly satisfactory degree of physical development. You see others work and strain without noticeable improvement for months or years. Quite often these latter cases come up with the time-worn excuse that they are simply not the type to gain. Some experts even have given various names to these unsuccessful barbell men and inform them with regret that they cannot change their type and they are therefore doomed to failure.
