Muscular Fitness
Muscular fitness is another important component of a fitness training program. Strength training at least twice a week can help you increase bone strength and muscular fitness. It can also help you sustain muscle mass during a weight-loss program.
Weight training is a type of strength training that uses weights for resistance. Weight training challenges your muscles by providing a stress to the muscle that causes it to adapt and get stronger, similar to the way aerobic conditioning strengthens your heart. Weight training can be performed with free weights, such as barbells and dumbbells, or by using weight machines.
Most fitness centers offer various resistance machines, free weights and other tools for strength training. However, you don't need to invest in a gym membership or expensive equipment to reap the benefits of strength training. Hand-held weights or homemade weights, such as plastic soft drink bottles filled with water or sand, may work just as well. Resistance bands are another inexpensive option. Your own body weight counts, too. Try push-ups, abdominal crunches and leg squats.
