1. I was playing today and noticed that whenever I get tired, my forehand is terrible. I use a western forehand grip so just to get decent pace on the ball, I have to swing hard. However, when I'm tired, I can't swing as hard so the ball just goes into the net. To compensate for this, I swing up more and end up lobbing most of my shots just to get it over. What should I do? When I get tired, it's not so much my legs that are tired but my upper body... 2. For all of my strokes, my hand is not completely on the racket. My pinky hangs off the racket and only my three fingers + thumb are on there. I don't know when I got into the habit of playing like this but it feels better for me. It feels like I can whip the racket better. is this bad? should I try to transition my whole hand back onto the racket? 3. When I first started playing tennis (4-5 months ago) I learned how to serve using a continental grip. I was horrible at it and got it in maybe once every three serves. Now today, I started serving with a mild eastern backhand grip and my serves are going in a lot more. is this an ok serve grip?
