One way you could get in shape to fend off bullies was to join a karate club.
This ad for Dempsey's Karate School is from 1972 and gives the lowdown on various aspects about the team and the club facilities.
My mate used to go to Dempsey's around 1969/70 and I remember going along with him one Saturday morning to watch a training session.
Afterwards, I got to muck about with some of the gear they had and this was the first time I had ever encountered a medicine ball. Blimey, I could hardly lift the thing off the ground, never mind throw it and catch it!
