Four-point kneeling
Commence in four-point kneeling with your knees bent at a 90-degree angle and the palms of your hands flat on the ground. Keep your stomach muscles engaged, taking care not to arch your back or tuck your pelvis under. Swing one knee forward and slightly off the ground. Touch your opposite hand to your knee.

Now extend your arm out above your head and extend your leg in the opposite direction. Remember to keep your stomach muscles engaged so that your torso stays in a straight, horizontal line. Lengthen your back leg towards the back wall.

Hold for approximately five seconds in this position. Repeat 10 times with one leg, then swap.
