Looking to model your strokes after Rafa but you’re a righty? No problem! Albeit the footage is from 2013, reinterpret_cast has some great mirrored footage of Rafa hitting as a righty in slow motion.
The footage is of backhands in the first few minutes. Forehands begin around the 3:00 minute mark. Watch for the strong forearm pronation that helps make his forehand one of the heaviest in the game. After pronation and releasing of the wrist, his is arm is left pointing completely straight at the target.https://www.youtube.com/watch?v=xvujEMnzQvs
