How has age and injuries affected your performance? George, I know you’ve had knees surgeries which limits your mobility in bjj. Does it hamper your tkd? In my case, I have some arthritis in my fingers. It mostly hinders my bjj, and I use more no-gi grips than the average person. Haven’t noticed a big difference yet in tkd; the flexibility loss is more from too many years away. It’s coming back quickly, but hip mobility is more of a concern than it ever was. Ive been fortunate otherwise. I hurt my back years ago, im sure i had a slipped disk, but i used common sense and gradually strengthened it and it doesnt hinder me anymore beyond knowing it will never be as strong. My knees, elbows, shoulders, hips have never had issues from tkd. Wear and tear from bjj though, so I spread out my workouts and crosstrain tkd in between. Anyone else deals with anything?

Does anyone really refer to the crescent kick/half-moon kick as described in the 2011 KKW technical terminology by ahn and capener? They describe the bandal chagi as similar to dollyeo chagi, but supporting leg does not pivot, like an ap chagi; and kicking leg is slightly turned in to strike. Most references i see to bandal chagi seem to take the older approach of it being an outward or inward kick (bakkat or an chagi), swinging the leg up to strike with the outer edge or inner arch of the foot.
