A home gym lets you get a serious workout into your day without having to leave your home. When shopping for a home gym, there are a number of factors to consider.
First, consider the space you have available. In addition to the space taken up by the machine itself, you'll need about 2 feet around the equipment for the person exercising. If your space is very limited, a single-stack gym is a good choice. There are also home gyms designed to fit into corners, which may help save space. If space isn't an issue, consider a multi-stack gym.
Next, consider what muscle groups you want to work and what kinds of exercises you want to do. Home gyms have many different types of equipment, including cardio equipment and equipment designed to exercise your upper and lower body. Consider all the exercises you can do with each home gym before making a decision.
