Factors that influence physical fitness include heredity, behavior, and environment. is this true or false?

I would say that this is true. Behavior plays a huge role in you physical fitness as part of your behavior includes your motivational skills. The enviroment can also greatly influence your physical fitness. For example, if you live in a somewhat isolated area with beautiful scenery and trails you will be more apt to hike as opposed to living in a big city. Finally your heredity also influences your physical fitness as certain traits may be passed on to you from your parents like height for example. If you are tall you will be more likely to play certain sports like basketball and volleyball. There are other examples where heredity plays into your physical fitness like if any hereditary diseases were passed on to you but for the likely hood of not being here for 5 hours typing I'm just going to conclude with saying that this statement is very true.
