Double kettlebell clean and press

Take care: Learn the double clean and the double press apart first.

Two 16 kg bells cleaned together into the double rack, then pressed to lockout; lowered to the rack and dropped back into the swing.

Load and joint demand

Load in the model: 16 kg each hand. 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

7/10 effort7.3fatigue per set

Your quota per set: 10 reps at 16 kg each hand, stopping 2 reps short of failure.

One hard set earns 182 legs points, 110 push points, 35 pull points, 46 arms points, 35 core points.

Prime movers

Gluteus maximus, hamstrings, deltoids, triceps, upper trapezius, abdominals.

What to look for

  • Clean both, settle, then press.
  • Ribs down; no leaning back to finish.
  • Elbows back on the ribs before the drop.
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.
