It's VERY intense. Thats what matters, the intensity of the training. Dont ask if someone found it good or found it bad, try it out for yourself and see if YOU make gains with it. Cause as we all know every body is different.
You might be worried that you wont make gains over the X amount of time you're trying it out, but thats cool, if not then you havnt done any damage. If it works, then thats ace and you've just found yourself a new way of lifting.
Goodluck with it
