Snatch-grip deadlift

Deadlift with a very wide grip, about 110 cm. The wide grip shortens the arms, so the hips must start lower.

Load and joint demand

Load in the model: 100 kg. Balance and joint demand re-solve as you change it.

Faults

Faults grow with knee bend and apply to lifts standing on the floor. The fault check flags a knee caving more than 10° inside the line of the toes and a load split beyond 60/40. Knee cave shows best in the front camera.

Body

Femur changes keep standing height fixed by shortening or lengthening the torso. Longer femurs force more forward lean in any squat.

Effort and your quota

8.5/10 effort8.9fatigue per set

Your quota per set: 10 reps at 100 kg, stopping 2 reps short of failure.

One hard set earns 246 legs points, 46 pull points.

Prime movers

Gluteus maximus, hamstrings, quadriceps, upper back, trapezius.

What to look for

  • Deeper start than conventional; see the knee angle.
  • Upper back works hard against the wide grip.
How the model works, and its limits

One 3D skeleton drives both views. Segment lengths and widths are Winter's anthropometric ratios of height; segment masses and centre-of-mass positions follow Dempster's data. For free-standing lifts the whole-body angle is found numerically so the combined centre of mass of lifter and load sits over the middle of the foot. Arms and legs use two-link inverse kinematics with a pole direction. Rep timing follows a minimum-jerk profile.

Balance is quasi-static, so ballistic lifts are shown slowed down. Cable pull and pad support forces are not modelled. The spine is one rigid segment and joints have no range-of-motion limits or muscle forces.
