Setup
- Place the bar securely on the upper traps or rear-delt shelf, never directly on the cervical spine.
- Use a grip that keeps the bar stable without forcing the shoulders; keep the wrists near neutral.
- Stand about shoulder-width with a natural toe angle and pressure spread across the whole foot.
- Inhale and brace so the rib cage stays stacked over the pelvis before unracking.
Execution
- Begin by bending the hips and knees together, allowing the knees to track in line with the toes.
- Control the descent for about three seconds while keeping the heel, big-toe base, and little-toe base grounded.
- Descend until the thighs approach parallel or lower, prioritizing a neutral spine and stable feet.
- Stay braced during the brief pause; do not relax or lose control in a bounce.
- Drive the floor away and let the hips and chest rise together instead of shooting the hips up first.
- Regain a stable standing position, breathe, and brace again before the next repetition.
Breathing
- Before descending, inhale and create 360-degree pressure through the abdomen, sides, and lower back.
- Maintain the brace through the sticking point; exhale and reset only after regaining a stable stance.
Common mistakes
- The knees collapse inward instead of tracking with the toes.
- The heels lift and pressure shifts excessively toward the forefoot.
- The lower back rounds noticeably or becomes excessively arched.
- The hips rise before the chest, turning the ascent into a good-morning pattern.
- The load or depth exceeds the range that can currently be controlled.
Safety
- Use an empty bar or light load first to confirm depth, balance, and a clear rack exit.
- Set safety arms or pins; use a qualified coach or spotter for demanding sets.
- Stop immediately and seek professional help for sharp pain, numbness, dizziness, or chest discomfort.
