An old tradition here on the blog is to have a Tuesday Tennis Tip. So, I'm reviving that for this season. Here is a great video about service toss. A number of people on the team are struggling to find their serve this year. Here is a professional, Florian Meyer, explaining the toss. Of course, the toss is the most crucial aspect if you want a consistent serve. So watch the video, then do it in practice tonight!
Here's some video of Sol, showing us what the instruction might look like if we can do it ourselves. This shows you some of the improvements that the above video could make.
Here's a video of Sol from the side, to compare to the video above.
