Walking Dumbbell Lunges strengthen the quads, glutes, and hamstrings while improving stability and coordination. Hold a dumbbell in each hand at your sides, step forward with one leg, and lower your back knee toward the ground while keeping your torso upright. Push through the front heel to bring your back leg forward into the next lunge. Alternate legs as you move across the floor. Gymcheq emphasizes controlled steps and balance to maximize results and reduce injury risk.
