Parkour moves: Cat Leap
With the cat leap, you can land to hang onto a wall. At the end of the
leap place your feet on the wall and grab onto the top of the wall with
both your hands. Your feet should touch the wall a little before your
hands. Bend your knees enough to make a soft and silent landing.
Things to take into account
Test the wall beforehand because it may be slippery.
Where to start
Try hanging on the wall in right position. Start with small leaps.
