Place weight securely on your back. Assume a push-up position, hands slightly wider than shoulder-width. Engage your core, maintain a straight line. Lower your chest to the ground, bending your elbows. Push through your palms to return to the starting position. Repeat.
Start with a manageable weight. Keep elbows at a 45-degree angle. Engage your core to maintain a neutral spine. Ensure weight stability. Inhale on the descent, exhale on the ascent. Use a partner for weight plate placement/removal.
