First, start doing things with your left hand more often...from eating to lifting always go with the left first. Force yourself to work the left moreso than the right.....that's one of the biggest problems for you righties...the left...every thing is designed to be used by your right hand....and us lefties benefit from it.. Seriously though...have you started throwing 1000 jabs a night yet....get your left used to it....act like you're stealing something out of someone's hand. reach out ..take it out of the hand..pull back before the hand closes...it's a visual thing.....
