TECHNIQUE: Standing straight up, hold a weight overhead with one arm and perform a walking lunge. While lunging forward: Activate your core to keep the torso vertical (shoulders should be over the hips); & Keep the arm vertical and fully extended. ADVANTAGES: This move not only challenges your lunge strength by adding extra weight, it works to improve your balance, coordination and muscle recruitment throughout multiple muscle groups. FAULTS: Torso leaning forward excessively; Knee tracking too far over the foot; SCALING: If holding a weight is too much for your core to keep stabilized, or too much for your arm to hold then begin with no weight and just holding your arm overhead and move up slowly in weight as you progress.
