I found a racquetball court, the wall is 30ft tall and 20ft wide, there are 2 side walls with the same height and about 30ft long, there is not a lot of wind get inside because of the tall walls. I dont have the exact measurements. When Im bore I use to go there and hit birdie against the wall, using underhand and driving strokes. I can't do overhand clears because the birdies dont bounce back far enough. I dont see I improve, what do you guys think?
it improved my smash defense as well as my lifts. before, i used to make short lifts. now my lifts are actually going too long. hahaha. need more control i guess.
hitting against a wall improves reaction time, you come out being able to hit faster with smaller swings. it's a valid drill. keep trying, do it right, get better. much better than being idle right?
