As superheroes we know the importance of being able to lift tons of weight, hone our powers, withstand ungodly amounts of pressure, posses a relentless motor for getting through any situation, and the greek god like body that can come from training all those things. You know what no one ever seems to talk about? The amount of cardio required in superhero work. I'm not talking about training even, just the day to day job requirement that is high levels of cardio.
You spend most of your time running to or away from things. Even if you're not dealing with a direct conflict, you're still walking during your patrol of the neighborhood. Quick question, how much energy do you think you would have left for bad guy shenanigans after forty five minutes of walking around the block, climbing buildings, and jumping from roof top to roof top? I'd say, rounded to the nearest whole number, zero.
The trouble is, training cardio sucks. It is absolutely the worst. It is painful, and gross, and a great way for seeing the inside of your stomach. But if you plan on saving the day, you have to include it somewhere in your program. All the greats do. Even the strongest most super powered hero has to work on cardio.
The Flash has super speed powered by the speed force, equally enhanced reaction and time perception, and has enough power in his sprint to bend, break, and travel through time. And he still had to practice running in order to do so because, cardio.
Superman is a Kryptonian alien with more powers, abilities and might, than most other teams of heroes put together. His power is fueled by our solar system's yellow sun. He has had most, if not all of his powers by puberty, and yet even he has to find time to huff and puff and hopefully not blow a house down because of accidental super breath.
Batman has every bat themed gadget you can think of, including an armored fleet of vehicles, and created a fighting system that requires one timely strike at a time to help him avoid as much cardio as possible. Yet he runs, swims, climbs, and of course conditions with sparring, you know, just incase.
Maybe, just maybe, it could be helpful to do a burpee, or run a sprint.
