HBP Main Character.png

BUILT FOR TENNIS. BUILT FOR THE COURT.

Develop the movements necessary for tennis through playing tennis.

YOU PRACTICE HARD. BUT ARE YOU TRAINING THE RIGHT FEEL?

Are you practicing very hard.

Even so, you want to swing faster. You want to hit the ball further forward. You want to swing through completely even in a game.

You want to take your first step faster. You want to hit shots that put more pressure on your opponent.

 

Such problems can sometimes not be solved simply by "trying harder."

What Heavy-Ball Pro changes is the environment it provides to players.

 

Change the load. Change the resistance. Change your focus on the point of contact. Change the stimulation from your feet.

By presenting the body with challenges different from usual, the players themselves feel, adjust, and adapt.

That's Heavy-Ball Pro training.

AccelBooster

A new tool to maximize your training results.

You want to swing faster. You want to stabilize your contact point. You want to swing without tensing up and fully utilize your own swing. This tool offers a new approach to addressing these challenges. What we create is a training environment designed to help players notice differences in movement. Using weight, resistance, and the feel at the point of contact as clues, players explore how to use their bodies effectively. They then apply the sensations they gain to their regular play.

A new tool to maximize your training results.
