5. Functionality. Exercising with free-weights increases the likelihood that the effects of the exercise will cross over into real-world situations. Think about it. How often during the day do you lie in a diagonal supine position and push weight up like you would on a machine leg press? Probably never. But how often are you required to do activities that are biomechanically identical to the squat? Sitting, getting in and out of a car, crouching down to pick something up?all the time! Properly using free weights will increase the functionality of an exercise to real-world situations.

6. Safety. It seems counterintuitive to consider free-weights as safer than machines. Most of us have heard (somewhere..) that we could get hurt with dumbbells and that machines were "safer." Maybe just the idea of someone doing a huge bench press lends itself to imagining the likelihood that one might lose control of the same amount of weight if they ever attempted it.

Safety during exercise is more about proper form, technique, concentration and control rather than exercise apparatus. Someone can get hurt on a machine just as easily as with a dumbbell if incorrect form is used. As always, if you don?t know how to do something, find someone (i.e., a reputable trainer) to show you how.

Safety as a result of exercise is a long-term issue. It is not necessary for the body to stabilize itself or the weight during movements on most machines, because the weight apparatus is fixed. Key stabilizer muscles are then never given the chance to get stronger. Free-weights allow the exerciser to utilize core muscles and allow multi-plane movement that forces the exerciser to strengthen stabilizer musculature, which support joints. Over the long-term, free weights are superior to machines for building a stronger, more functional body.

You don?t need to spend a fortune on a piece of exercise equipment that you?ll never end up using and won?t suit your needs. A few sets of dumbbells are effective, intelligent alternatives to buying equipment, especially for those setting up their own in-home gym or workout area.
