Jason Blaha stated this from several studies he had seen, he said.
He admitted strength AND cardio are best though.
One study at a university, in my country actually, suggested that running just 20 min 3 times a week is best for the heart. More is not better when it comes to avoiding early death.
This fact may indicate the little "cardio" we get from doing sets and reps are significant heartfriendly aswell.
What do u think?
