Strength Training and muscular strength are just one component of physical fitness. Strong muscles are essential for supporting the skeleton and enables ease of body movement, good posture, decreases risk of injury, and overall performance of everyday activities.
Strength training is beneficial if your muscles are weak. It can help make you stronger and improve your balance and flexibility. Strength exercises work your muscles by using resistance like dumb bells, resistance bands, weight machines or your own body weight. This type of exercise increases lean muscle mass, which is vital for weight loss or weight maintenance because muscle burns more calories that other types of tissues.
Most physical activity guidelines recommend doing strength training exercises at least two to three days per week. The major muscle groups in the body that requires training include the legs, hips, back, chest, abdomen, shoulder and arms. Start with a low weight, you may even use your own body for resistance, and slowly build up as you feel stronger.
