My fellow friends, you make it abundantly clear that lifting is the way to go if one wants to become strong and fit. But does anyone here have any experience with Calisthenics (body-weight training).

If I could, I would honestly just go to the gym and lift. But given my age (17) I am still under the jurisdiction of my parents. Both of them are medical doctors and they have a firm belief that going to the gym may interfere with my growing process.

So are calisthenics a valid alternative to lifting?
