Yeah you have to go about it pretty slowly but i swear on everything rear delts get a real good hit from this and ive added a nice amount of size in the last 3 months by throwing this in with some heavy military thrown in .....try it even with light weight you feel it ...and overall its one of those things that makes it really hard to cheat...try like some 20lbs dumbells bro!!!!!it looks cool....for a baseball player or olympic swimmer
but honestly......for an ADVANCED bodybuilder
that workout would be a disaster waiting to happen
its got INJURY writtin all over it
ALL my shoulder moverments are short and powerful
none of this "rotating" bullshit, that makes me wince just watching
sorry man
