Liu Shiwen and Guo Yan training (rare footage!) 

hm.. that's like what i do except my tempo is faster, but i did notice her transition fh to bh was much better. i need to analyze this :)

Who said table tennis is not exhausting? I do mad strength & conditioning training but tellin ya Liu Shiwen got maaaad cardio. I kid you not when I say this is super tiring!
