I don't know much about cheerleading... or what cheerleading entails in adulthood.
I'm an electrical engineer and a salsa dancer. I am fortunate enough to live in a big city with a vibrant salsa dancing scene. I have performed and participated in competitions and have no problem keeping up with dancing alongside engineering.
In fact, I know at least 3 other engineers who are actively performing and training at our studio.
So it should not be a problem to keep up with the cheering unless it requires extensive periods of travel or conflicting with work schedule.
