Stand in front of a step with a resistance band loosely looped around your wrists.
Bend your elbows to point your fingertips towards the ceiling with your palms facing each other.
Maintain a neutral spine and engage your deep abdominal and shoulder blade muscles throughout this exercise.
Simultaneously step up onto the step with one leg as you reach your arms overhead into a "V" position, pressing out gently into the band.
Pause at the top of the movement then step forward with your other leg as you control your arms back down to the start position.
Pause, then push back onto the step as you reach your arms overhead into a "V" position, pressing out gently into the band.
Pause at the top of the movement then lower back to the start position with control.
Repeat.
