Rotate wrists to unrack, extend arms above your lower chest. Lower the bar with control to touch your lower chest, elbows at 45 degrees. Press the bar up, squeezing your chest, and extend your arms. Maintain retracted shoulder blades and a braced core. Repeat and re-rack.
Maintain a flat back. Control the movement, avoid bouncing. Engage your core. Adjust hand placement for comfort and muscle engagement. Warm up beforehand. Inhale on the lower, exhale on the press.
