Step 1. Stand with the feet together and the arms by your sides. Separate the feet slightly further than shoulder distance apart. Inhale and raise both arms straight out from the shoulders parallel to the floor with the palms facing down.
Step 2. Exhale slowly while turning the torso to the left, bend at the waist and bring the right hand down to the left ankle. The palm of the right hand is placed along the outside of the left ankle. The left arm should be extended upward. Both legs and arms are kept straight without bending the knees and elbows.
Step 3. Turn the head upward to the left and gaze up at the fingertips of the left hand. Inhale and return to a standing position with the arms outstretched. Hold this position for the duration of the exhaled breath. Exhale and repeat on the opposite side.
The triangle pose is basically doing slow toe touches while concentrating on your breathing and stretching your body.
