Since the forehand is executed with the dominant arm, it is typically the first tennis stroke that anybody learns. If you are right-handed, your right arm and wrist would be used to strike the forehand. If you are left-handed, you would use your left arm and wrist to strike the forehand. Some people can use both hands equally well because they are ambidextrous. Use the same arm you use to throw the ball for your forehand.
The palm of the dominant hand carrying the racket should be facing forward when you swing your forehand. In essence, the tennis forehand is created by swinging the racket across the body in the desired landing direction.
The topspin forehand is the most commonly used forehand during baseline play. Flattening out the stroke is often a feature of high-performance players games when they are inside the baseline and/or advancing toward the net. The slice forehand is rare at all levels of the game and is generally used as a defensive stroke When playing under pressure.
Key features of the forehand of beginner and intermediate players thus, include the following:
A balanced, relaxed and comfortable ready position followed by a sound footwork.
A continuous and rhythmic racquet swing/trunk rotation adapted to the oncoming ball.
A semi-open/square stance at impact to contact the ball in front of the body.
A smooth follow through that follows the path of the ball and finishes across the body.
