I've been practicing Aikido for 6 months now, but I can't accomplish a good ukemi all the time. I'm 6'4" and I weight 300 LBS. I move now very fast and with more agility, and most of the techniques I performed them without any problem, But ukemi is my down FALL
. I got hurt the first time I tried, I almost ripped a ligament in my shoulder and it hurts since then. Can you help me to improved my falls?
