IMO, we get a lot of bodyweight/callisthenic questions. The problem I find is that no one ever seems to like the answers. It always seems like people want to look like Phil Heath and they're disappointed when a pure calisthenics program isn't making them monstrously muscular in 2 months. What do you mean I have to change my eating habits? Blasphemy.
And if you're coming from a heavy weight training routine at the gym to a resistance-bands-from-Walmart home-workout routine, the sad truth is you're gonna lose gains.
Rant aside, if you've got a specific bodyweight question that hasn't been asked before (try searching
[home-exercise] first) feel free to ask it. Lots of really experienced individuals are knowledgeable in body-weight exercises.
