Tennis is by legs. All the opponents were spying his toss to find whether it is a slice or kick or flat serve. But, he wisely used his legs to adjust his body position for the same toss. For kick serve, he moves his front leg half a feet on his right. No opponents found this even after his retirement 😂😂
His serve has changed since this video, the start position of the toss is higher and the elbow stays at 90 degrees until the racquet drop. Also quite a bit of the floppy wrist is gone, though it is still very relaxed. His current serve is very simple and easy to copy (except for the flexibility 😜). I have a much harder time trying to copy Federer, the toss is super difficult, that slow down at the trophy phase always blows my timing as well.
