Unless we're talking about the calisthenics we did in school gym class, circles with your arms, you can get pretty big and shredded with it. Calisthenics is basically gymnastics and gymnasts are much bigger than yogis.

Really nice handstands! I was also going to say you definitely can get very, very strong just doing calisthenics. Mike Tyson famously was doing pretty much all calisthenics until the 90s. Here's him fighting a 30-0 Spinks -- who reportedly didn't even want to leave his locker room for the fight he was so intimidated by Tyson -- training mainly calisthenics up until this point. I'd say Tyson was pretty strong. https://www.youtube.com/watch?v=HuaFIRD7_5Y

No knock on weight lifting though, it's great. But for most people getting on a yoga mat and doing some calisthenics is a lot more approachable than learning how to use a gym properly for their bodies.

Serious Gymnasts also lift weights at specific points in their overall training. It’s faster and helps avoid bad habits to have the strength to do specific moves before attempting them. This is especially true after injury.

However spending hours a day doing gymnastics is plenty to maintain that level of physical strength and even slowly improve.
