Do I need any equipment to start calisthenics?
Very little. A floor and a sturdy bar to hang from covers the vast majority of training. A pull-up bar, and eventually parallettes or rings, expand what you can do, but you can make real progress with bodyweight alone.
That's exactly why calisthenics is ideal for training at home or while traveling—I program around whatever you have available.
