Based upon this thread, http://theofficebodybuildingworkout28918.yuku.com/topic/11217/Performs-Routine-Day#.WOWWB02gvIU , I decided to do some research. I was surprised, actually, appalled! Appalled, I tell you! by the number of people who do the same exercises every day. I am and always have been a steadfast proponent of split routines in which you recover from the previous day's exercises. I found three pretty good articles that explain the whys and wherefors of recovery, and which pretty much bear out what I've been doing all these years:
This one is very technical:
This from the above:
Recovery after exercise is essential to muscle and tissue repair and strength building. This is even more critical after a heavy weight training session. A muscle needs anywhere from 24 to 48 hours to repair and rebuild, and working it again too soon simply leads to tissue breakdown instead of building. For weight training routines, never work the same muscle groups two days in a row.
I would contend that bodyweight and to-the-max isometrics is akin to weight lifting.
