Some treadmills fold up for storage, making them a good choice for those who want to burn calories and get a good cardio workout with reduced impact to knees and other leg joints. They typically do not fold up and can tend to take up more space than other equipment and will almost always cost more for quality equipment. It may also be important to have instructions before using some features of the gym to avoid injury. Traditional home gyms may have free weights and barbells, or be machine-type gyms with several stations and functions attached to a single steel frame. A free weight system is good for exercise enthusiasts who are knowledgeable about proper form and technique for lifting weights. For less experienced users, though, a machine-type gym offers most of the same benefits while helping to ensure good technique by using prescribed motions. A traditional home gym usually requires quite a bit of space so you should make sure your home can accommodate the size and weight of whichever model you select. Do not put your treadmill in a garage or any other space
