Cardiovascular endurance - Train like a firefighter

Firefighters need cardio endurance to perform prolonged jobs. These are often made even harder by hot environments, wearing heavy protective clothing and using heavy equipment. The heart is another muscle in the body that needs to be trained, just like your legs. High intensity interval training is one of the best ways to do this and will improve your cardiovascular endurance.
