I just wondered if anyone has had some of the issues I've had, coming from playing tennis. I've done a bit of coaching now, and the coach is trying to get me to shuffle forward rather than run. The coach pointed out that I often hold the racquet with both hands, and I wasn't conscious of how much I was doing it. I found that sometimes I did it to change grip. I'm in the process of stopping that, and I only did it once at the start of the last session. For the time being at least I feel a bit awkward. It's actually quite strange switching to tennis from mainly playing badminton. The first time I did I had a look at the racquet after the first two shots to verify if it was mine, as it felt like a rock!
