The walking lunge is one of the biggest bang-for-the-buck exercises to add into your weekly programming. This is how I use lunges, along with leg extensions, as a finisher on leg day.
Reasons to Lunge
It both requires and builds core strength.
It challenges stability and balance.
It improves flexibility through the quads, hamstrings, and hips – aiding in injury prevention.
It works the body unilaterally.
Increasing the load via dumbbells works grip strength, traps, and back in addition to the lower body.
Increasing the distance or shortening the rest breaks makes it a fantastic fat burner.
