Every skill sits on a foundation

When posture and balance fail, skill cannot be expressed. The bundle trains both ends of the performance triangle: the base that holds you steady, and the chain that delivers your power.

01 / THE BASE

Gravity Belt 2.0

Variable resistance pulls your hips toward the ground, so you naturally adopt the ideal athletic position. Stay lower, hit cleaner, outlast your opponent.

02 / THE POWER

Kinetic Band

Rotational resistance gives you instant feedback on energy transfer through hips and shoulders. More power, better timing, cleaner shots.

03 / THE WARM-UP
Free Mini Bands activate glutes, hips, and shoulders before every session, so you get more from every rep.

Training with the Gravity Belt on court

Stay Low. Hit Bigger. Miss Less.

The Gravity Belt uses Reactive Neuromuscular Training. Resist the tension of the bands and your body learns to hold a lower, stronger stance under fatigue and pressure.

Control. Improve coordination through Reactive Neuromuscular Training.
Hit cleaner. Keep your base set through every shot.
Strength. Train athletic positions with up to 20 kg of resistance.
Outlast. Challenge your endurance and stay balanced late in matches.

Effortless, Consistent Power

First seen with Djokovic's long-time fitness coach, the Kinetic Band adds rotational resistance so you feel energy move from your hips, through your shoulder, into the shot.

Pro power. Feel explosive energy transfer through the hips.
Ground your game. A strong base is required to balance against the resistance.
Better timing. Heightened awareness means more efficient shot production.
Technique boost. Big, inefficient backswings get eliminated.

Rob R., Ex Pro

Better balance, quicker recovery steps, and more confidence chasing difficult balls. It trains movement naturally, without overcomplicating things.
