Pattern
Hip hinge
Setup
- 01Set the bar across the upper back and grip it tightly, pulling the elbows down.
- 02Step back from the rack with feet about hip width apart.
- 03Set a very slight, fixed knee bend that will not change during the set.
- 04Brace the trunk and set a neutral spine before the first rep.
Execution
- 01Push the hips straight back and let the torso tip forward.
- 02Keep the bar over the mid-foot as the chest lowers.
- 03Descend until the hamstrings stop the movement, usually near torso parallel.
- 04Drive the hips forward and stand tall without hyperextending at the top.
Checkpoints
- -Knees stay nearly straight so the hamstrings load through a long range.
- -Spine stays neutral from setup to lockout.
- -Hips travel backward, not just the shoulders tipping down.
- -A strong hamstring stretch, not lower-back strain, limits the depth.
Common mistakes
- -Rounding the lower back to chase extra depth.
- -Bending the knees progressively and turning it into a regular good morning.
- -Loading it like a squat; this movement punishes excess weight.
- -Losing the bar forward by letting it slide up the neck.
Programming notes
- -Use 3 sets of 6 to 10 reps with modest loads, roughly 20 to 40 percent of your squat.
- -Excellent hamstring accessory on deadlift or squat days.
- -Add load slowly week to week; hamstring and erector tissue adapts slower than the movement feels.
