Hi all. I have access to a heavy bag on some days... but on most I only have access to a freestanding (wavemaster). You know those TKD popular punching bags. I was wondering what kind of drills I could execute on that particular type of bag that would work my footwork. Im in desperate need of some improvement in the foot work area. Also... what are your favourite hand combos? I like jab/cross/hook/cross but I need to get proficient at some other ones. Thanks all
