improving your plyometric ability will help with one foot take off

seeing as though you cant train though, i would just keep practicing your one foot take off and trying to perfect it/improve on it.
did you read my thread??

i think you would find it very usefull

keep practicing with smaller sized balls and go up the sizes

get your ankle injury taken care of before starting any training again

proper static strecthing done 3-4 times a day will pay off.Great with training and in season aswell, helps with recovery and achieving optimal performance.

static stretching before bed and after in the morning is good, also after session/games on training/competition days.
