Camp Rhino is hosting an Ultimate Ninja Athlete Association regional qualifier and the top three ninjas in each age bracket will have the opportunity to go to Albuquerque for nationals.
Ninja competition offers a different way to get in shape and a wide range of age levels with seven-year-olds being the youngest to no age limit for adults.
"Everybody encourages everybody," said Rick Gray who will be competing tomorrow. "It makes going to the gym fun."
Competitors can expect a wide range of obstacles that require a number of different abilities.
Veteran ninjas point to grip strength and upper body strength as being the most important, but in addition, balance is key as well as a can-do attitude.
Both Camp Rhino and Bodies in Motion are gyms that have obstacles where people can practice to become a ninja.
