No opinions. It's just like gasing or yo-yo. If you use a heavy enough gasing or yo-yo, you might gain a wee bit of strength. But that's not the purpose of gasing or yo-yo or Powerball.
If you think you'll enjoy using/playing it, why not?
Not everything has to be about building muscles or getting bigger.
+1. do whatever you think its more fun. its not exact science, this. as long as you're having fun and you get satisfactory gains, i dont see why not. BUT, it is true that dumbells are better since you can train more than just your armsIf you think you'll enjoy using/playing it, why not?
