One reason why people stall (and few seem to want to take this to heart) is because they work out TOO FREQUENTLY.
If I were a powerlifter, I would do 5-3-1 three days a week. This has you doing each lift every 8-9 days. And if you've been lifting awhile, you NEED that sort of recovery.
Plus, studies have shown that muscles require 7-10 days to recover from a training session! With that in view, why would you want to come back and work it two days later ?!?
That's like determining that 15 minutes in the midday Sun is optimal for a suntan. Then resting for five minutes and coming back out in the Sun!
The exception is for people who just don't train very hard. If you just go through the motions, terminate a set when it becomes mildly uncomfortable (as most do), then sure, you should be able to train more frequently. But why would you work out this way ?
