11. some sort of explosive arm swing exercise, could be hip dominant or not, ie plate swings, db swings, hang snatch, etc.
Would doing explosive dumbbell swings upwards consistently for a few weeks actually give a significant increase in vertical (1-2 inches)?
i'd have hands locked, ie, two hands on one dumbell or using a plate to swing.. if you don't have very powerful shoulders already, then yes it can help and give a few inches, who is to say how long though.. but arm swing is a very important part of any type of jumping, so by really getting those shoulders powerful, itll definitely have some carry over.. doing things like plate swings, double arm db swings, and snatches can all be very beneficial, though snatch variations are much more hip driven, that's why something like a plate swing can provide even more benefit for arm swing "from the bottom"..
really keeps those arms locked out and try to derive most of the power from the shoulders, i need to vid one day how i do it, i sit into it, arms locked grabbing the plate, and really try to swing up using ONLY shoulder power, but of course I use a little bit of hip also.
i would avoid db swings with one in each hand though, can get a little risky for the shoulders.
peace
