Con

Bit of a silly topic unless you state the goals set out when doing these programs; strenght, speed, hyperthrophy.

But all criticsm no comment is rubbish so my two cents....
Training body parts more frequently but not to failure is very good for a power athlete and beginer body builders wanting to add easy to gain size.
Con is once you get advanced your power and recovery reserves will dip due to training so often.
Training every thing once per week at most is great for advanced hyperthrophy aiming athletes and if the proper mind set is there nothing adds size and power to the slow gaining advanced trainer.
Con its very hard on the joints.
