Strength training, also known as resistance training, is a type of exercise that involves contracting muscles against an outside resistance. This resistance can come from a variety of sources, including body weight, weight machines, medicine balls, resistance bands, or dumbbells. The goal of strength training is to strengthen and tone muscles, and it has many health benefits, including:

• Increased muscle mass: Helps to maintain muscle strength and function and improve general physical function.
• Improved bone density: Helps to prevent osteoporosis and reduce the risk of fractures.
• Better weight management: Helps to increase metabolism and burn calories even after the workout is over.
• Improved balance and flexibility: Helps to maintain independence in aging.
• Reduced risk of chronic diseases: Helps to reduce the risk of heart disease, diabetes, and certain types of cancer.

When starting a strength training program, it is important to consult a doctor first and start slowly to gauge how much your body can handle. A beginner should train two to three times per week to gain maximum benefit. It is also important to choose exercises that align with your goals and pick exercises that target different major muscle groups. A strength program should focus on strength, hypertrophy, power, and muscular endurance. The workout should also include proper safety and form to reduce the risk of injury.
