A better oftenly, but shorter.

What will a benefit, as prolonging trains for two times/week or short, but very oftenly exercises within a week?
A good is non prolonging exercises,as every time when organism attacking a loads,metabolism processes and circulation of blood in an organism will raise,therefore everyday loads and non prolonging,as ideal variant. And prolonging trains,will load poor on a half train, and on this time a not long exercises will cover you as maximum, and prolonging trains a few times/week are tiring, and poor effectively, in often trains a muscles within a time will stop hurt.
