Using free weights is an effective way of improving strength and fitness. Lifting weights improves fitness while it burns calories, increases muscle size, strength, power, and endurance, and increases bone density. It also increases bone density and improves quality of life for many older adults. Instruction is necessary if you have never used free weights before, or are not that familiar with the use of free weights. Technique and safety are important considerations.
Unlike weight machines, free weights don’t restrict movement. This is great for building strength, but it also increases the risk of injury. Safety precautions include having a good grip, maintaining a stable position when sitting or standing, using good technique, and getting good instruction from an exercise professional.
