Strength training builds strong muscles, improves heart health, promotes weight loss, increases bone density, and helps protect the joints and back. Building muscle strength will create a leaner, tighter body and improve looks. Strong muscles will also improve mental functions and boost the energy level. Strength training comes in the form of selectorized, plate loaded and free weights. Free weights come in various forms: barbells, dumbbells and kettle bells. One of the biggest advantages of free weights is the ability to do several different movements in one exercise. This is also known as Functional Training. Having the equipment so easily accessible in the privacy of your own home not only saves time but it makes it easier to fit workouts into an already busy schedule.
