The 'bowling pins' on the floor in the photo on the left are actually Indian Clubs. The British imported them from India and introduced them to the UK, Europe and North America. It was during the colonial occupation of India that the British were first introduced to the Indian Clubs.  Impressed with the physical fitness of the Indian men who were fighting in the British army, the British soldiers integrated the clubs into their regime. Much like the kettlebell, the clubs are meant to be used in a swinging, dynamic motion. They range from 5 lb to probably well over 100 lb. I tried them out at one of my kettlebell certifications and I could barely manage 20 lb.
