Hey sorry for the late reply... yeah I incorporated handstand work for shoulders as well as pull ups and front lever practice on a beam. I also worked on L-sit to handstand support for core.
I thrived for years by walking and biking.. until I saved enough money to buy a car for cash. I rented rooms for 180/ month with college students and cooked rice for dinner :)
I do have a gym membership now because I really enjoy the barbell and dumbbell, I think they are a great inventions to achieve previously impossible loading patterns.
I like your lifestye :)
You might even be better stoic than me :D
