Peripheral Heart Action (PHA) training is a system that tones up muscles throughout the body and works in cardiovascular exercise at the same time. Some of the benefits of PHA workouts include saving time, all over conditioning and cardio training. It can also be a big enough change from your regular routine to add fun and interest. By alternating upper and lower body resistance exercises, mixed with short periods of cardio activity, your heart rate stays elevated throughout the session, and this conditions the heart while the resistance exercises tone and strengthen the body. The action of changing from upper to lower body exercises makes the heart work harder to move blood from one end of the body to the other.

How long you can hold your breath gives a rough idea of the condition of your lungs, their maximum capacity, and their ability to oxygenate your blood. The average person can hold his breath for about two minutes, but practice can help you hold your breath for increasingly longer amounts of time and will improve lung function. When you are relaxed, you need about 6 litres of oxygen per minute, however when you exercise, the demand increases significantly and can go as high as 60 litres or more, depending on your level of fitness.

Resting heart rate is measured while the subject is at rest and awake, and not having recently been involved in exertion. The typical resting heart rate in adults is 60–80 beats per minute. Resting heart rates for athletes can be well below 60, with values of below 40 bpm not unheard of. Maximum heart rate is the highest heart rate a person can reach without severe problems through exercise stress and is directly related to age. Maximum heart rate shows a slight but steady decrease of about 1 beat per minute each year beginning at 10 to 15 years of age.

In almost all muscle work outs, the most overlooked area would have to be the neck. Most people neglect to give it much thought, but that can be a mistake for several reasons. It really doesn’t matter what sport or activity you are involved in, your neck muscles play a major role. Always remember to use caution in doing any neck muscle exercises. Warm up first and rotate your neck from side to side. To increase flexibility, use a full range of motion. If you experience problems, see your doctor.

This energy comes from the fats, carbohydrates, and proteins in the food you eat. Of the three, fat is the most concentrated source of energy because it furnishes more than twice that for a given weight than protein or carbohydrate.
