Exercise is a cost of recreational activities

Explanation:

Recreational activities are often done for enjoyment, amusement, or pleasure and are considered to be "fun". Most of the time these activities are used to get healthy that is why they contain exercise. For example some recreational activities are abseiling, backpacking, coasteering, cycling, camping, canoeing, canyoning, caving, fastpacking, fishing, hiking, horseback riding etc. We can see that all of them need exercise.
