Incline bench press

Barbell on a 35° incline, grip about 80 cm. Bar travels from straight above the shoulders to the upper chest.

Load and joint demand

Load in the model: 70 kg. Balance and joint demand re-solve as you change it.

N·m now / peak over the rep.

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

4/10 effort4.2fatigue per set

Your quota per set: 10 reps at 70 kg, stopping 2 reps short of failure.

One hard set earns 246 push points, 64 arms points.

Prime movers

Clavicular pectoralis major, anterior deltoid, triceps.

What to look for

  • Bar touches higher on the chest than a flat bench.
  • Lockout sits straight above the shoulder joints.
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.
