Wide-grip bench press

Grip about 96 cm, well outside the shoulders, elbows out a little further. The bar travels a shorter distance and touches a little higher on the chest; elbows placed by 3D IK.

Load and joint demand

Load in the model: 80 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

4/10 effort4.2fatigue per set

Your quota per set: 10 reps at 80 kg, stopping 2 reps short of failure.

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

Prime movers

Pectoralis major, anterior deltoid, triceps brachii (less than a standard grip).

What to look for

  • Hands about a thumb's length wider than your normal grip, forearms still close to vertical at the touch.
  • Shorter range than a standard bench: keep the shoulder blades pinched to protect the shoulders.
  • Bar touches mid-chest, a little above the standard touch point.
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.
