Channel Description

"Putting the FUN in Fundamentals of Tennis" Hey there Ramon Osa with ya here, and if you’re looking for step by step tennis techniques tactics and strategies made simple designed to take your game to the next level… then you’re in the right place. Ya see, unlike a lot of other very good youtube tennis teachers, I wasn’t a natural athlete… I didn’t start out playing competitive tennis at the age of 4… in fact, tennis was my first official “sport” and I didn’t pick it up until I was 16 when I was literally 50 pounds overweight and tired of sitting in front of the tv all day. So you'll find step by step tutorials, humor, and a lot of other good stuff!
