I'm starting to make some progress on my serve, and it feels amazing. All those days where serving feels like some foreign thing over the past few weeks are worth it. I think I'm serving bigger than ever, maybe even close to 100 mph (as if it even matters). My biggest issue was my toss, but in the process of evaluating everything I realized I should bring my shoulder lower, keep my arm looser, and feel a bit lighter on my feet. Making these minor adjustments have helped the consistency of my motion. While I still am not at a level where I feel I could play a match and serve consistently in at whatever pace spin I expect of myself, or even keep the ball in consistently at all, I am only missing the service box by a foot or a few inches. This isn't negligible, but I am happy with it. There is one problem though. I can't figure out how to brush up on the ball. Whenever I try to, I still hit it in a way that does not give it enough spin to be second serve. This is my next goal. So, I encourage anyone who has made an improvement in there game to post here. It is such a relief, and after a few days where I honestly thought about quitting tennis, I feel reinvigorated.
