First of all, what is a lever?
In its simplest form, a lever consists of a rod pivoted on a fixed point known as the fulcrum. The lever transmits an input force in order to provide a greater output force to raise or move a heavy load. This input force is leverage. |

Imagine your body is the fulcrum and the shovel shaft is the rod.
As your arms spread out across the shaft to grasp and control the shovel, you are able to apply force at one end of the shovel – its handle – to achieve a greater force at the other end – the blade. Hence, your arm span acts as the lever. |

So, whether you need the extra force to dig out an awkward shrub that refuses to budge, or to shovel heavy loads of snow, a wider arm span will give you that additional balance and power. In other words, you have greater leverage. | |||
