Does it mean that learning these styles would be sufficient to replace gym sessions? Does it build muscular and cardiovascular strength?
It is far more comprehensive than gym sessions. The training is physically, intellectually and spiritually much more demanding and technically advanced, as things like weapon and freehand training build more dynamic, supple and flexible muscles, tendons and joints compared to weight training. Also, it has the specific purpose of postural correction not found in normal gym sessions. The internal training involved, such as Qi Gong practices, is more therapeutic than mere cardiovascular exercises as it tonifies and develops the Qi and lymphatic system in addition to the cardiovascular system. Additionally, the neural, skeletal and immunity systems are targeted for enhanced performance and are also repaired and maintained.
