There’s a popular saying, “Nothing is a guaranteed.” But a new basketball training tool is trying to change that notion. For players hoping to improve their game, Guarentee3 might provide a boost in both training and performance on the court. And all without the expenses of a personal coach.

Becoming the next Steph Curry might be a stretch, but why not shoot for it? That’s what Guarentee3, the training kit for improved basketball skills, wants to instill in up-and-coming players. Creator of the Guarentee3 trainer Dave Felkel got the idea after his son told him he had a weak shot.

“I developed Guarantee3 to be used anytime, anywhere so you can train without a ball or a court.”

“My goal was to focus on strengthening the shooting arm and rapidly improving dribbling skills,” said Felkel. “So I developed Guarantee3 to be used anytime, anywhere so you can train without a ball or a court.”

The trainer, which is worn around the waist and shoulders, straps on like a lightweight backpack. Targeting muscle memory, agility and proper shooting mechanics, the Guarentee3 is suitable for all court athletes no matter their competition level, gender or age.

Easily adjustable, the stretch band is designed to keep the player’s hands at the right level for optimal shooting, dribbling and ball handling. The intentional placement also instills muscle memory, so eventually the player will move optimally without help from the trainer.

Each Guarentee3 kit includes a body harness and five stretch bands, one workout glove, a conventional travel bag to transport the harness, and six unique workouts targeted to improve basketball techniques. Find out for yourself if it will work for your customers or young athletes.
