I have a not so fond memory camping out in Walmart for my Wii. I think we could just stay inside since it was 24hrs and they were selling them right at midnight.
I got home, turned on the Wii, and was asked to insert a startup disc. I searched that box at least 20 times trying to find the disc with no luck.
I was a heavy user of GameSpot's forums at the time and asked about this disc. Literally everyone thought I was trolling. Nobody believed me until I uploaded photos of my TV.
Eventually my dad called Nintendo and they shipped out a new one ASAP but my 16 year old self was so pissed given all the hype going into it. Days waiting with a useless Wii staring back at me.
That's because it's generally hard to build enough volume in the abs for them to show, given that fat tends to store in the belly, covering them. As such it's often said that you get abs in the kitchen rather than in the gym, but that's about a low calorie diet.
What the post above talks about is about taking enough calories and protein for you to be able to build muscle, normal diets very rarely include enough to build muscle optimally and it can be harder to actually eat enough than to lift enough.
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.
