The History of Air Alert
Air Alert is one of the most popular vertical jump programs on the market.
It is also the oldest, and the “grandfather” of all vertical jump programs.
The first version of the program (Air Alert I), was created by TMT sports in 1991.
It was a huge success and became very popular all around the world.
The main reason is because it was the first program of its kind, and it also guaranteed that you would jump higher or get your money back.
Several upgrades have followed over the years: Air Alert 2, Air Alert 3, and the latest version is Air Alert 4.
