Why do I always foot fault?
The reason tennis players foot fault, is some players move the incorrect foot towards the baseline, if you’re right-handed player your weight transfer should be with your back foot, in other words you’re right foot, if you’re left-handed player the weight would come forward with your left foot. Players step sometimes due to ball position, they step on the front line or the baseline with the front foot and they’re trying to make an adjustment to their line or position under the ball. They try to set themselves underneath the height of the ball due to their poor toss on the serve. This is why people foot fault and strike bad tosses and make bad serves.
