All Kung Fu styles have their strengths, but one they all share is strength of the lower body, or leg strength. They all employ low stances so as to be able to root themselves for offensive as well as defensive movements.
The twelve ton tois that we train are actually sets of movements which are designed to work on your stances. Ton toi means thunderkick in Chinese. Low stances gives a practitioner a lot of jumping and kicking power as well as excellent cardiovascular training.
So lower your stances!
