Extend your left arm outward that they are directly lying flat in front of you. Use your right arm as a brace and plant your palm properly on the floor. Raise your right leg a little bit above the ground and then straighten it outward slowly. If you cannot make a 90 degree angle, then simply move your leg farther. Hold this position for 5 seconds stretched out as far as you can during this time. Repeat the process for 12 times before you turn over and do the same process on your other side.
