Exercising regularly not only helps you keep slim, but also improves your overall health and well-being. Different exercises produce different results, as they focus on alternate parts of the body.There are four broad exercise categories: endurance, strength, flexibility, and balance. Many people often only focus on one exercise type, but including all four in your workout will produce better results and reduce your risk of injury.
Endurance
Endurance exercises increase your breathing and heart rate. By doing endurance exercises, you are working to keep your heart, lungs, and blood-flow system healthy while improving your total fitness.Over time these activities will make everyday activities seem easier.
Strength
If you want to build up your muscles, then strength exercises, which are also known as "resistance training", are right for you. Even the slightest increase in strength can make a huge difference in your ability to carry out daily tasks. Developing strong muscles also reduces your risk of weak bones.
Flexibility
Flexibility exercises help stretch your body's muscles. This allows for more freedom of movement for other exercises and can also improve your range of motion, posture,ability to breathe deeply, and blood flow. Also, it reduces the muscle tension caused by stress.
Balance
Balance exercises help prevent falls and are especially important to older adults, helping them stay independent. Most good balance exercises are ones that keep you constantly moving with your feet on the ground. Heel-to-toe walking and standing on one foot are simple ways to improve balance.
