i heard that those exercise will improve ur footwork reaction alot .. i had done those exercise for 4 days a week and each days ,i do 15 minutes skipping .. but i usually do the skipping pattern like this : jump-rope passes-jump-jump-rope passes-jump-jump and so on .. is that way will improve my footwork ? btw ,is it ok to do big exercise after eating ?or should i rest first ? if so ,how long ???
