To improve your Padel serve, focus on proper setup and court location, move immediately to the net after hitting, maintain a legal contact height around the waist, use mainly slice spin, aim for a medium-to-fast speed with good depth and accuracy, utilize the bounce for forward momentum, and approach the serve with intention and focus.
If you're looking to make your serve more effective, this lesson is very helpful. The coach gives practical tips on everything from where to stand to how to hit the ball and what to do immediately after. Focusing on these points can really help you start points more strongly and get to the net faster.
