So I'm an decent player. Played a lot of singles in high school. As a result, I could lift pretty well and high deep serves weren't a problem at all. But one day this week, I woke up and went to play and my lifts were TERRIBLE. No accuracy, nor precision. It was like the birdie had a mind of it's own. Earlier this week and last week, while playing, I had noticed that when I lifted to start the bird off while just rallying, the bird would often go off to the right a bit. Now, my lift control has totally gone out the window. My lifts were accurate and precise before. For example, in singles games, I preferred to serve high and deep to their backhand corner, and the birdie would go there. Sometimes, I'd say to myself: okay, I'm going to serve to their forehand corner.. and the birdie would oblige. Now, when I tell myself I'm going to lift to a certain place with a certain height, it never goes there. And I can't even lift well while I'm just hitting around with people. It goes in all directions. Obviously, I'm slicing the lift sometimes. But even when I consciously correct for it, my control and placement still stink. What happened? (no injuries recently, arms and wrist and whatnot are fine) What are some methods or drills I can do with myself to correct this? Thank you for your help.
