As the summer Olympics have officially commenced in Rio de Janiero, Brazil, most people are preparing to watch the many sports that are a part of them. Many Americans, and people around the world, are surely anxiously awaiting the swimming, track and field, soccer, bach volleyball and gymnastics competitions. However, there are many more sports that are a part of the Olympics that most people probably don't know about. With that being said, it is interesting to note some of the lesser-known and sports that are a part of these Olympics year after year.

1. Trampoline

This may be one of my favorite unknown Olympic sports. Most kids grow up jumping on trampolines and these people get to perfect that craft and become professional athletes in a sport that is pure fun for most people.

2. Walking

Yes, walking is a sport in the Olympics. It is placed under the umbrella of track and field, but there is multiple events in speed walking. Isn't in crazy that you could become an Olympian just for walking...something most people do every day?!

3. Handball

Handball is like soccer, but with your hands. It's an extremely interesting sport to watch, and one that competition has already gotten underway in this year's Olympic games.

4. Cycling

Most people know of the track and road cycling competitions. However, there are also competitions in both BMX cycling and Mountain biking. These are both intense competitions which will undoubtedly be exciting to watch.

5. Marathon Swimming

The pool swimming competition is one of the most watched in all of the Olympic games. However, another swimming competition does take place. Marathon swimming is swimming in open water of a distance of 10 kilometers.

Personally, I am excited to watch all of the most popular sports as well as the ones on this list and many more including rugby, diving, and table tennis. Basically, I will be watching the Olympics 24/7 until they are over. Whether you are an avid Olympic Games watcher, or someone who just watches a few events, there is something for everyone this year in Rio.
