Thus 50 kg (~491 N) of plates will apply to the user only an equaling weight of 18 kg or a force of ~174 N at the beginning of the motion. On the other end of the spectrum may be a bent-over-row machine that is designed with the user's grip between the plates and the fulcrum.

The lifting of anvils requires competitors to lift an iron anvil or ingude weighing 18 kg (40 lb), 30 cm (12 in) above the height of their own head, as many times as possible in a set time period. The anvil has the shape of an obtuse triangle with a stump at one point or an elongated T and is traditionally used in shoeing horses.
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
