As a Tennis Professional, I have worked with additional weight on the body in different ways (ankle straps, filled belts and arm straps) on searching for a way to enhance Performance, Speed, Strenght and Endurance.

None of them has allowed me to be confortable enough to actually be able to practice at a normal level on a Tennis Court.

There is a possibility to put more weight on, but I tried it and it resulted in two much weight for Speed or Power exercises, although I liked it for Biking and Jump Exercises.

You should be careful anyway the first days because the first trainings could cause muscular problems or Pain until the body gets used to the extra Kilos.

Anybody can use the trousers for any training purpose, and enhance performance for probably any possible sport and after just 10 to 15 sessions start feeling that extra inch of Power and Endurance that could make the difference between losing and winning.

So, I highly recommend the use of Hasanen Weight Trousers for anybody, professional or not, who wants to enhance Body Performance on any Sport.
