Most people work out at a gym, lifting weights, treadmills or bikes. I get my work out by training in Karate. To me it’s a lot more fun than feeling like a hamster on a treadmill. And on the plus side if you practice real karate under instructors who know what they are doing you learn something useful as well. The required concentration and perfection of martial arts also appeals to me at a deeper level.
So it’s a lot of fun when things happen in karate that allows me to take photos. Just such an occasion occurred when our senior students finally (some waiting years) got their black belts. As an acknowledgment of their martial prowess they get to first defend themselves against everyone (one at a time) with various limitations like not being allowed to use their hands. And than they get to spar with some of the more senior students.
