1. Load a barbell with weight plates and attach chains so they hang evenly on both sides. 2. Stand with feet wide (sumo stance) and toes slightly pointed outward. 3. Grip the bar with hands inside your legs, keep your back straight and core braced. 4. Drive through your heels and extend your hips and knees to lift the bar off the floor. 5. Keep the bar close to your body and stand tall, squeezing glutes and hamstrings at the top. 6. Slowly lower the bar back to the ground under control.
Log your weighted chain sumo deadlift sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
