Weight Ratio

Some machines feature complicated pulley systems and do not reflect the actual weight you are lifting.
1:1 Ratio – this means that the machine has no mechanical advantage and that you are lifting the weight which you have loaded on the carriage/weight stack.
2:1 Ratio – this means this machine’s pulley system provides a mechanical advantage and you are lifting half of the loaded weight.
3:1 Ratio – you are lifting a third of the loaded weight.
