Stand up straight with a resistance band tied in front of you.
Hold the other end of the resistance band in both hands around the height of your navel, and pick up the tension.
Keep your posture up straight and stand on one leg.
Maintaining this posture, steadily move your hands directly forwards, straightening your elbows out.
The band will try to pull your body forwards.
Use the strength in your abdominal muscles to resist this movement.
Do not allow your shoulders to hunch.
Control the movement as you bend your arms, bringing your hands back in to your body.
