Lifting the weight like the person on the left produces a greater torque about the lower spine (pivot) – the lifting force is at a greater perpendicular distance to the pivot. The back muscles must exert a huge force to provide a torque that balances the torque from the weight being lifted.
It is important to lift a heavy weight close to your body to reduce the torque produced around your lower spine.
