Take a pronated (overhand) grip, hands closer than shoulder width but not completely next to each other, position yourself underneath the bar. Start with your arms full extended, shoulders depressed (down, away from your ears). Squeeze your glutes and brace your core, your body should form a straight line head to heels. Maintain this position throughout.
Begin by retracting the scapula (Flexing your shoulder blades together) Engaging your mid back, before flexing your elbows and pull the bar to your chest.
Squeeze at the top, mid back engaged, lower to the start. Repeat for repetitions.
Be sure to initiate each rep with your scapula and not your arms, and maintain total body tension.
