deltoids and trapezius workouts ?

[Dice]

I was wondering since I am new to the whole powerballing buisiness a few things :

1) I acertained from the information that powerball doesn't increase muscle mass significantly, but I was wondering does it add definition ?

2) is there a workout that targets the deltoids specifically?

3) can the powerball be used to work the trapezius ?

thanks a lot for any replies :D

I dont know about 2 or 3, but as for your first question.

People say it doesn't add much mass to your muscles but for me it has. My biceps are about 2-3 inches bigger which is a significant increase by anyones estimations. It has taken me 18 months to get that increase, and the fact i'm spinning in excess of 15K means the force on my muscles is over 40lbs. It also definitly increases definition in your muscles.

I wonder if Physioblue is still secretly reading these forums....
