I currently train in TKD and in 1 week I start bjj, I am looking to eventually do some mma once my skills develop and I see how I fair with others. I am thinking of switching to a MA more suited for MMA but currently I like TKD and I want to atleast get my BB in a couple years before moving on. But for now I was wondering if anyone who trains in TKD when doing bag work do you modify your kicks from hitting with the ball or top of the foot to hitting with the shins or does anyone know if this is ideal? We loose a bit of range by doing this but from what I see kicks are alot harder when hitting with the shins. Any info whether from a tkd practinioner or not would be greatly appreciated.
