If you want to hit a flat serve hard, hitting with only your arms will not make the ball faster; instead, it will become unstable. In this video, we explain in detail the mechanism used for the flat serve and the principle of power transfer, which follows the sequence of legs → rotation → upper body → arms → racket. A serve is not simply the motion of swinging the racket quickly, but rather a process of connecting the power generated in the lower body to torso rotation, shoulders, arms, and the racket. We also explained why you should utilize the side of the ball, rather than hitting it head-on—a point many people often overlook. Rather than presenting the perfect answer, this video focuses on the core principles to help you understand the flat serve. 🎾 Timeline 00:00 Introduction to the Flat Serve Mechanism 00:45 The Truth About Poor Serves Limitations of a Serve Hit Only with the Arms Why the Ball Goes Weak Even with Power Problems Arising from Relying Only on the Wrist and Arm 04:10 Principles of Power Transfer Ground Reaction Force Starting from the Legs Torso Rotation and Energy Accumulation The Flow of Power Connecting the Upper Body, Shoulders, Arms, and Racket 08:20 Why You Must Do It This Way A Strong Serve Comes from Connected Motion, Not Arm Power Why the Entire Body Must Move Like a Chain Why Racket Speed ​​Comes Aligned with Rotation and Timing 12:30 Why You Must Hit the Side of the Ball Why Power Dies Out When Pushing the Ball Straight Ahead Why Utilizing the Side Allows the Racket to Move Faster Why a Sense of Rotation Is Necessary Even for a Flat Serve 15:30 Wrap-up The Key to Flat Serve Power Transfer Summary Key Points to Check During Practice Small differences can make a huge difference in a tennis serve.
