I have been playing tennis for many years, and a consistent failing point is my serve. Yesterday, I had a bit of inspiration and decided to try and rework my serve a bit.

I was amazingly lucky to find something that felt consistent (at least for one day) and most importantly - that I felt comfortable with. However, I had concerns.

We know that a foot fault is when your foot touches the baseline before you make contact with the ball. However, I pose to you what may be obvious, this - what if your feet are planted, and your toss meets or exceeds the baseline...forcing you to lean over the baseline with your body?

My feet are behind the baseline the whole time, but my shoulders and head are meeting or past the baseline at point of contact. I felt this gave me a great intertia and forward momentum to hit the ball.

I was however, unsure if this was even legal. Help me out here!


I couldn't find anything about this in the ITF/USTA Rules, and players very frequently have their body over the baseline. Take a look at this slo-mo video of Roger Federer serving. He (and most other pros) always lean slightly into their serve for the exact reason you specified. It's fair game as far as the rules are concerned.
