Resistance Equipment
For some people free weights are not ideal and they much prefer to purchase resistance machines. The most common of resistance equipment is the weight machine. These weight machines (http://en.wikipedia.org/wiki/Weight_machine) use gravity and a system of weights and pulleys to give resistance to the person using the machine. Adjustments can be made to the machine that allows it to be a long-term investment that adapts as your fitness level grows.
Other types of resistance machines that are available are Friction machines, spring-loaded machines, fan-loaded machines, fluid loaded machines, hydraulic equipment and whole body vibration machines.
In home gyms there can be the limit of space and many companies have realised that an individual usually cannot find the space for several machines. To solve this problem many companies have found ways of combining the purpose of several machines into one specialised home resistance machine. This is a fantastic solution both cost wise and space wise.
