Regardless of the sport, the ability to rapidly and efficiently accelerate, decelerate, change direction and move a body segment or the entire body rapidly is a nearly universal and essential element of success.


At the Academy of Sport Speed and Agility we focus on perfecting the explosive acceleration that gets you to the ball first, or allows you to hit the line at your maximum speed possible.


Our specialised training programs and excellent team of coaches will get you running faster, for longer, through perfect speed and efficient movement mechanics.


Podcast excerpt (0.48) : "Our kids don't play enough anymore... movement issues in our developing youth"

The ASSA training system has been designed for progressive athletic development in speed mechanics, acceleration and force production (strength) to make you run faster, for longer.

Based upon decades of experience and world-class research, we specialise in youth long term development for explosive sport speed and reduction in injury through perfect movement mechanics.

The programs are a huge success for all field and court based sports players aged 9 and above and are easily implemented into your pre or post season training plans.
