If available, you can use a cable machine for this exercise.
Alternatively, fix a resistance band to a solid object above your eye level and hold the end on the same side you will lunge towards.
Stand up straight and engage your deep abdominal muscles.
When ready, simultaneously perform a lateral lunge by stepping out to one side as you pull the resistance band towards your chest with your elbow tucked into your side.
Return to the start position with control.
Repeat.
