TECHNIQUE: Start with your feet hip width apart, active arches and braced core. Shift your weight back into your glutes and hamstrings to the point where your glute is parallel with your knees. Maintain your balance and braced stomach as you curl the sand bell up and down. Shoulders are back and retracted. ADVANTAGES: The Sand bell Squat Crush Curl is great for working arms, legs and core simultaneously. This movement requires a tremendous amount of concentration and muscle recruitment. FAULTS: Common faults include not hitting depth in the squat, shoulders and rounded and pushed forward, and or low back is flexed from lack of core engagement. SCALING: Movement can be scaled to a squat then curl to reduce the amount of time under tension. The challenge of the movement comes from the isometric hold in the squat pattern.
