Escalators to help you warm-up

We all say walking to the gym can be a great warm-up and save your time. Our question here is, what is the point of all the weight lifting and bodybuilding if you cannot climb 15 stairs? It is a pity if you need an escalator for a task as simple as this, so it’s better to be home and never come to the gym. And, the gym owners tell us what is the purpose behind the gym if you have these escalators and people depend on such machines instead of working hard in the gym.
