Body 4 Life is a great program. Everything about it is reasonable and healthy, AS LONG as you don't lift into pain. Fatigue is different than pain, so make sure you are lifting "to fatigue/failure" safely, and doing the lift motions right (slow up, slower down.) "Lifting to failure" means you cannot do one more rep SAFELY AND CORRECTLY - NOT "when you drop the weights on the floor."
(if you did this before, Vinny, you know this, just a note for any who might be thinking of doing the program.) The book is really clear and well laid out, making this an almost foolproof system to follow.
I've been thinking of starting again myself.
