How to use this lift in training.
Position and movement cues
- Grip
- Grip the bar evenly and pull it into the upper back so the torso feels braced before unracking.
- Feet
- Use a stance around shoulder width with toes slightly out. Keep the whole foot rooted through the rep.
- Back and chest
- Brace the trunk, keep the chest proud, and let the torso angle match your squat style without collapsing.
- Range of motion
- Descend as low as you can control while keeping balance and foot pressure. Aim for at least thighs near parallel when mobility allows.
- Speed
- Lower under control, keep tension in the bottom, and stand up with steady pressure through the floor.
- Elbows and knees
- Track knees in the same direction as toes. Do not let them cave inward as fatigue rises.
Common mistakes
- Knees collapsing inward
- Heels lifting
- Relaxing at the bottom
- Good-morning the bar out of the hole
How to practice it
Start each set by finding the same setup: stable feet, balanced grip or handles, a braced trunk, and a repeatable start position. Stop the set when the lift no longer looks like the first good rep.
For a heavy barbell lift, use the empty bar, then a few smaller jumps before your working weight. For dumbbells or machines, use one or two lighter feeler sets.
Loading and progression
Use 3-6 reps for strength practice, 6-12 reps for most muscle-building work, and 10-15+ reps for lighter accessories or skill practice.
Pick a load that feels like RPE 7-8 on the final set. Add weight only when the target reps, range of motion, and positions stay consistent.
Track it in RackMath
RackMath keeps previous weights, reps, RPE, plates, warmups, and PRs connected to the exercise so the next session starts with context.
