A conventional deadlift with 140 kg lowered over four seconds instead of dropped, keeping the bar close and the back flat all the way to the floor. Same set-up and balance solve as the deadlift.
Load in the model: 140 kg. Balance and joint demand re-solve as you change it.
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.
Femur changes keep standing height fixed by shortening or lengthening the torso. Longer femurs force more forward lean in any squat.
Your quota per set: 10 reps at 140 kg, stopping 2 reps short of failure.
One hard set earns 292 legs points, 35 pull points, 35 core points.
Gluteus maximus, hamstrings, adductor magnus, quadriceps off the floor, spinal erectors, lats.
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.
