Stand up straight with a resistance band looped around your upper back, holding one end in each hand.
Bend your elbows to approximately 90 degrees.
Maintain a neutral spine and engage your deep abdominal and shoulder blade muscles throughout this exercise.
Simultaneously lunge forwards diagonally across your body onto one leg as you punch your corresponding hand forwards and round your shoulder blade against the resistance of the band.
Ensure you keep your upper back straight.
Pause, then return to the start position with control.
Repeat, leading with your other leg and hand.
