Ancient Greece Kettlebell training
“ A warrior said that he could lift a bull over his head. Everybody laughed and so he bought a new born calf. Every day he raised the calf over his head. As the calf grew so he got stronger. Eventually he could raise a bull over his head and nobody laughed any more.”
