Lunges are a fantastic functional lower body exercise, and the benefits can be enhanced by adding an upper body component to the basic lunge movement pattern. One of the most productive total body lunge variations is the reverse lunge with a diagonal lift.
The exercise improves hip mobility in the front of the rear leg, while also increasing strength and stability in the front leg and increasing core strength and mobility. Specifically, it improves hip flexor mobility while training the body to move smoothly in the spiral line. It also encourages proper tri-planar movement.
Start standing with feet shoulder width apart in upright posture. Hold a medicine ball, dumbbell, or kettlebell (or even a body bar) positioned at the right hip pocket region. Step back with the right leg to perform a reverse lunge. At the same time move both arms diagonally up and back over the left shoulder until a comfortable stretch is felt in the anterior (front) of the right hip. Do NOT allow the back to arch. Pause in this position for one or two seconds.
Do 10 – 15 repetitions on one side then repeat on the other side. It is important that you keep both feet facing forward and keep your trunk upright throughout the movement.
Perform the movement without a medicine ball, dumbbell, or bar
Start in the split stance lunge position instead of having to step back
Increase weight you are holding.
Perform the movement in an alternating side manner vs one side at a time.
