Sometimes laughing isn't the best judge of what's funny 'cause I think there's a lot of things that are really funny that don't make you laugh that don't make you physically audibly make a noise but is something that is much more powerful than that.
One killer exercise that's really great is pull-ups with your legs out level. That's my favourite. It's such functional core strength and that's why I can climb up trees and down vines.
