Free weight machines and free weights differ in the respect that free weights can be moved freely in a concentrated area of space. Free weight machines are restricted to moving in one of two directions.

Home workout equipment often consists of one machine that will perform a variety of functions and the machine easily converts to a heavier weight by simply inserting a pin in a block of weights, or by adding weight plates, or by adding a band. Some of the most widely known are:

• Total Gym uses the body weight of the user and elevation – the more extreme the elevation, the more difficult the workout. Never underestimate the body as a weight in strength training – and this unit folds up to be rolled into a closet or under a bed.
• Bowflex, by Nautilus, has two types of machine, the progressive, resistance cable, pulley system with power rod units; and the linear resistance, interlocking, lightweight resistance plates – both are geared for the home user.
• Weider makes the Ultimate Gym package, (four people can work at the same time) and single user machines, a Bowflex machine, a sled type of machine that resembles the Total Gym, and separate machines for isolating certain muscle groups like the Smith Rack & Bench. Weider is one of the longest running names in exercise, weight lifting and competition, and workout equipment and machines.
• Body-Solid carries a large choice of machines for the home user. Most are geared for a full workout/weight training regime but a few specifically target certain conditions; the G8I claims to allow you to work primary muscles and secondary muscles due to 3-deminsional independent motion giving more defined muscle development. Almost all machines are guaranteed for life and most are listed as being commercially rated.
• Yukon has a variety of workout machines, mostly geared to single or two user stations and a few have no leg press available. Yukon has a specialized lat machine and delt machine available.
