The Shot-Put Serve (Don't Pronate)

Get "Crush It!" here: https://bit.ly/3xVRN9I

If you want more serve power, then try the "Shot-Put Serve" technique.  It was invented by Dr. Mark Kovacs, who is one of the world's leading experts in tennis biomechanics (how your body should be moving when you hit a serve, forehand, or backhand).

The point of the "Shot-Put Serve" technique is to develop long-axis rotation, which is how the shoulder, arm, and wrist should be moving when you swing up to the ball and hit.

Most people think, "Oh I gotta pronate," but pronation is just the forearm and wrist, it's only part of the equation.  Check out the video for the full picture, and let me know how much more power you get in the comments :-)
