What makes modern forehands so different from the strokes of the past?
Simply, the power is from the ball to the shoulder (or nearby), where in the past the power was applied from the backswing to the ball.
Further, today’s power is across rather than the linear idea of old.
The ball may be gone already, but the acceleration applied right at the impact makes the racquet-head’s windshield-wiper faster well beyond.
In the conventional forehand finish, the racquet pointed towards the placement. The modern forehand’s racquet ends up pointing back, behind the player. The butt of the racquet, rather, points to where the ball just went.
The two-handed backhand follows that model as well.
The new DVD, the Best of Oscar Modern Tennis Methodology, emphasizes this aspect. Make sure you avail yourself of it. It’s a superb guide to improve every stroke in your game.
