WILD LEGS: Drills or Training aids ?
My 2BK is awful (just saw it on video). Two problems:
a. Legs spread too wide (knee angle = 90deg) - drag+instability
b. ankles are also too stiff and 90deg - drag
1. Is there any training aid or drill which can help develop a proper kick (where legs stay within the CORE BODY shadow)?
2. Would it help if I tie my legs with a rope and swim?
