If you are new to the padel, it is best to choose a racket that is not too heavy. Padel rackets generally weigh between 330 and 385 g. A lighter racket is easier to use and gives you more control of your strokes. If you suffer from tennis elbow, a lighter racket is a good option since it is easier on the elbow.
A heavier racket provides more power in the strokes, but it can be clumsier and more difficult to use. Thus, it is more demanding of the player and therefore suitable for a more experienced padel player.
