Free weights have long been the base upon which all bodybuilding exercise has been based; however, these days lifting free weights, including olympic free weights, hand weights, exercise weights and dumbbell weights are used for other purposes too. Using lighter free weights or power blocks, one can form muscle definition, not just bulk tissue growth. Barbell free weights and other weights by Ivanco and Hampton are brands that we here at Global Fitness recommend that you as a consumer try to find. We also carry used free weights. Another advantage to you, as a consumer, to buying free weights as apposed to selectorized strength machines, is that free weights are far less costly. The typical free weights package is fraction of the price per pound compared to that of the traditional exercise machines that are currently available. One last point to make considering an advantage to free weights is that free weights take up less room and have very little to no maintenance and typically last a lifetime. Please take into consideration that body posture and exercise movement is a learned skill, using machines does have that advantage over free weights.
