Whether you are a world-class athlete or just the average person trying to keep in shape, the principles that ensure an extended life in fitness remain the same. Fitness expert Vern Gambetta once said: "You can't make an athlete in one workout, but you can break an athlete (client) with one workout." Training should always be structured and should progress along proper scientific principles; it should never be ad hoc or rushed.
Some people equate a great workout with being very sore. However, while a certain degree of soreness may occur a day or two after an intense workout, soreness should not be the gold standard by which you judge a good workout. Any trainer can make you sore, but that doesn't necessarily mean you had a great workout. If I were to hit you with a roundhouse kick on your upper thigh, it would make you sore, but that's not good for you.
Principles of Training
Warm-up–A proper warm-up is essential before any physical activity. A warm-up signals your muscles that they are about to be used. However, many people confuse stretching with warming up. Stretching forms part of a warm-up, but it does not constitute the entire warm-up. Never stretch a cold muscle. You should first perform slow, gentle rotary movements to literally heat up the muscles before you begin static and dynamic stretching.
Cool-down–Cooling down properly after an intense workout is just as important as the warm-up, because it helps to bring your heart rate, etc, back down gradually to a normal state. During exercise, muscle fibres, tendons and ligaments undergo a lot of strain and waste products build up inside the body. A proper cool-down will help the body flush the toxins and release the strain. If exercise is suddenly stopped, blood and other waste products can stay in the muscles; this may cause swelling and pain. Athletes refer to this as 'blood pooling'. A structured cool-down ensures that blood returns to the heart in adequate quantities.
Core training
Core training is essential for all athletes and physical fitness enthusiasts, because it helps to prevent serious injury to the body. Many people think of the core as just the stomach and lower back muscles, but if you think of a variety of sports, such as karate, squash, soccer, cricket, American football, etc, the control of your arms and legs during acceleration requires recruitment of many more muscles other than just abdominals and lower back muscles.
That is why I prefer to describe your core in this way: imagine your body without your head, arms and legs; what you remain with represents your core. It is important that you strengthen your core muscles through a variety of exercises, because these muscles will then be able to transmit power efficiently to your arms and legs. Follow correct training principles, listen to your body when it talks to you and you may still be vibrant and physically active going into your 80s and beyond.
Keep Training.
