Let's say it loud and clear: most of Vovinam instructors and masters only do arm-locks for the exams. Instead of working them all year long, the arm-locks are set apart in our work-out.
To be an effective martial art, Arm-locks must be practiced, and improved. The Khoa Tay Dat number 4 and 5 in Vovinam are NOT effective nor worked properly. This must change.
