INTENSITY offers a world-class tennis academy led by Adam Altschuler, Kris Hrisovulos and Mike Slattery indoors at INTENSITY. Unlike traditional programs, this 21-week session from November 2nd gives total flexibility to accommodate changes in school schedules. You purchase a pre-paid block of clinics and then sign up online by the day for the clinics you want to attend.

The program follows the USTA’s system of scaled training and competition for kids which is an exciting play format designed to bring kids into the game and improve their skills before advancing to yellow ball. The program is divided into two levels:

Next Generation: Orange Ball

Next Generation Green and Orange ball players are year-round committed players looking to establish technical/tactical foundations to their development. The primary focus of the training is stroke production and development. This program is offered six days a week and players competing in the program are required to train a minimum of 2 days per week.

All players are automatically enrolled in a 1½ hour Saturday match play where learning from the clinics is put into the context of a competitive match. There is no additional cost for match play and we anticipate players will not be able to attend every session due to conflicting tournament schedules.

Next Generation: Green Ball

The clinics are 2 hours in duration, the majority of which is on-court, with an element of off-court movement, footwork and overall coordination training with our certified strength and conditioning coaches.  The program is limited to 4 kids per 78’ by 27’ court and use 25% slower tennis balls that bounce at a level proportionate to a child’s height.
