Let's be honest. 

Your grandfather didn't need gloves while he worked long hours in the field or factory doing manual labour that would crush even the toughest of the so called "athletes" of today.

His hands were made of hard earned leather. 

He didn't "workout", he worked. Period.

Many of us train for the coveted "work capacity", but who among us would have had the work ethic to stand among the giants that were our forefathers?
