Home gym information

Many reviews say a set of dumbbells or free weights can be a great alternative to a home gym. They're cheaper, easier to use and can be incorporated in many different exercises. Free weights are not as safe (there's more leeway in which to strain or pull a muscle due to bad form, and heavy weights require a spotter), so you should also consider investing in a session with a personal trainer or picking up some literature on proper training with free weights.

Some machines can also be dangerous if not used properly. In an interview with Men's Health, Gary Guerrero, P.T., A.T.C., director of the U.S. Athletic Training Center in New York City, warns, "some machines are outright dangerous." Guerroro names three such machines found in commercial gyms, including a standing-calf-raise machine (which can hurt the back), a Smith machine used for squats (which can hurt the lower back) and the pec dec, which "places tremendous stress on the front portion of your deltoid, which can lead to nerve injuries," according to Guerrero. Machines can also undergo wear, which can potentially cause safety issues. In 2004, Bowflex recalled 42,000 machines due to an unstable lat tower and in 2005 recalled 17,000 Ultimate 2 Home Gyms due to a cable that could become detached, striking the user.
