How to dance the "mountaineering step" in the dance

The two legs alternately do elastic a bend all the time action. Remember that the legs must be flexible, the left leg when bending (heel off the ground) the right leg must be straight, the right leg when bending (heel off the ground) the left leg must be straight, the action should be fast, 1. can be done in place to do the action. 2. can be done forward to do the action. 3. can be done backward to do the action. 4. can be done left and right sideways to walk to do the action. It's not difficult, more practice, more understanding, will certainly be able to jump. The hiking step is very useful! It's a disco move, it's a cowboy move... I wish you success, my friend!
