Excellent post.
Horrible post.
If you can't do the same exercise everyday, then I guess the USMC, Army, Navy, Air Force, and other branches of the Armed Forces are all wrong. I at one time could do 75 straight push ups because of doing them everyday in the Marine Corps.
And as mentioned by Rosie, full body routines are actually ideal for beginners because of the opportunity for the use of progressive overload more times per week than just once. Not to mention, full body routines also put more overall stress on the endocrine system and therefore has a greater release of testosterone and other anabolic hormones during workouts.
Splits didn't show up until steroids started getting popular anyway. I'm not saying anything negative about steroids, I'm just saying splits work better generally for someone on juice and full body tends to work better for people that are natural or just starting out.
Muscle just doesn't need seven days to be trained again. Muscle actually can repair in as little as 48 hours.
