What's the most important training aid to help develop correct side/back kicks. What is the best pad or shield for practicing these kicks? I have practiced these kicks on, curved shields, Thai pads, body shields, blast pad(the thick but squishy pad) I think that's what it's called, and I've worked them on the heavy bag. Personally I liked the curved shield and the blast pad best for practicing these kicks. Any technical tips or equipment recommendations would be greatly appreciated.
