You can sign up for a membership at a fancy gym or you can fill your garage with expensive fitness equipment, but the truth is you don’t need to spend a penny to get in shape.

Here are five no-gym workout myths and misconceptions, and the facts to debunk them that might make you reconsider your plans.

Myth: It’s impossible to build muscle if I don’t go to the gym.

Reality: Many people want you to believe that the best way to build muscle is with expensive equipment that helps you bulk up. Sure, it is easier to build muscle with equipment, even if we’re just talking about a set of dumbbells, but the truth is you can build muscle anywhere using only your own body weight.

Resistance training and cardio that include repeated and rapid movements to strengthen and build muscle tissue are using nothing more than your own body weight.
