Remember this guy?

Jack LaLanne - Wikipedia

I remember watching him on tv in early 60s when home sick from school

amazing guy

I’ve seen him in clips. American fitness man.
He came after the “boxing a kangaroo” generation of these guys. Not being any sort of expert, I would think he was maybe one of the first modern type trainers.

Jack was a pioneer in bringing health and fitness to the masses and the feats he accomplished well into advanced age was just incredible.

A very uplifting and inspirational man.
