These weights can be used in different directions and forms to target specific muscle groups for either gaining muscular size or increasing calorific demand in the area for toning. For example, the underarms can be targeted by lifting the weight to the sides of the body along the shoulder rather than folding upwards towards the chin. The value behind free weights is the virtually limitless freedom to adapt your work-out to target which ever muscle group you choose.
