Pike push-up

Hips high in an inverted V, feet on the toes. The trunk rotates about the hips so the head lowers toward the floor between the hands.

Load and joint demand

Bodyweight exercise: the load slider has no effect here; body mass comes from your limits.

No gravity-based joint demand to show for this exercise.

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

3.5/10 effort3.5fatigue per set

Your quota per set: 13 reps at bodyweight, stopping 2 reps short of failure.

One hard set earns 182 push points, 64 pull points, 82 arms points.

Prime movers

Deltoids, triceps, upper trapezius.

What to look for

  • The more vertical the trunk, the closer it is to a handstand push-up.
  • The head goes forward of the hands, forming a tripod.
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.
