For heavy loads and max efforts, use the Vasalva maneuver. Val-what? The Valsalva Manuever is a technique that involves taking a deep breath immediately prior to lifting and holding that breath while you lift. Using this method, “You’re creating a lot of intra-abdominal pressure,” Tamir explains. This increase in pressure creates a strong foundation for your body and allows it to handle more weight. Before approaching a max-effort deadlift, for instance, lifters would stand over the bar and prepare for the lift. Right before setting their grip, they would take a deep breath in and hold that air inside the lungs throughout the rep.
