On the right forearm and the edge of the right foot, body straight. Built upright and rotated onto its side, so the side view shows the front of the body and the balance is side-to-side. Static hold.
Bodyweight exercise: the load slider has no effect here; body mass comes from your limits.
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: hold 38 s, stopping 2 reps short of failure.
One hard set earns 38 legs points, 109 core points.
Obliques, quadratus lumborum, gluteus medius.
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.
