Attach an exercise band high in front of you.
Stand with one leg forward and hold the exercise band with the opposite hand.
Roll your shoulders back and open your chest by contracting your lower shoulder blade muscles.
At the same time pull the exercise band down and move your trunk forward beside your straight arm, straightening your hips.
Your trunk should move forward and chest up.
Do not let your arm go past your bodyline.
Return to the starting position.
