Funny thing is they are only doing one work set Per exercise. Not even very challenging.
you're obviously one of those who think that several, non max sets is harder than one all out set.
i guarantee that you've never trained hard in your life.
until you've experienced what an all out set is, you are not qualified to comment. so shut up.
if you can do more than one all out set, then you didnt go all out. thats how you can tell.
do you need some more help with this?
