key swing thought: strings face downward and the torso rotation brings the strings to 90* at impact w/o manipulating / twisting the racket ....right wrist stays flex'd back thru impact
spinny forehand .... envision the racket butt cap as a roller coaster ....goes down then whips up ...finish the swing ... car (cap) goes all the way around the shoulder
Figure 8 swing ....right hand loops in to out ....circles back in ...and swings in to out .... This is the biometrically correct way to minimize effort in the swing and the power source is the hips/torso ...NOT ARM !!
