According to Jacobsen, Yoga has five principal meanings: Raja yoga originally denoted the ultimate goal of yoga, samadhi,  but was popularised by Vivekananda as the common name for Ashtanga Yoga, the eight limbs to be practised to attain samadhias described in the Yoga Sutras of Patanjali.
Medical journalist Dr Michael Mosley, like many people, is not a great fan of exercise for its own sake, and set out to find how little he would need to do to get fit. Challenging Current Thinking "It goes against everything I was taught in medical school, and everything I have ever read since", gasps Mosley to camera, as he completes a vigorous bout of pedalling on a stationary exercise bike while scientists look on.
Mosley, who trained as a medical doctor before moving into journalism and broadcasting, introduces the one-hour programme, "The Truth About Exercise", by saying that what he discovered about exercise, thanks to the latest research, has challenged his view, and altered the way he lives his life.
High Intensity Training A main theme of the TV programme is High Intensity Training HITwhere you do a number of shorts bursts of intense and effortful exercise with short recovery breaks in between.
HIT is not new, but has come to prominence in recent years as more researchers have looked into and measured its health benefits. There are various forms of HIT, depending on the intensity and duration of the effortful bursts, and your fitness goals.
Recent HIT research shows, for example, that doing ten one-minute sprints on a stationary exercise bike with about one minute of rest in between, three times a week, is as good for improving muscle as many hours of less strenuous conventional long-term biking. Professor Martin Gibala and his team at McMaster University, Hamilton, Ontario, Canada, carried out a study on college students, and discoverd HIT delivers the same physical benefits as traditional endurance training, even though it takes considerably less time, and surprisingly, involves doing less exercise.
Types of HIT In Gibala 's student study, the participants had to pedal at their maximum possible effort level on a specially adapted lab bike. The thinking then was that "all out" was an important part of the HIT method. But then, inGibala and colleagues published another study in The Journal of Physiology, where they showed how a less extreme form of HIT worked just as well for people whose doctors might be a bit worried about them adopting the "all out" method, for instance those who might be older, less fit and overweight.
In Timmons' form of HIT, the bursts of high intensity are at maximum effort, but of very short duration 20 seconds at a time. Timmons told Mosley, who was doing no weekly exercise at the time, that he could expect to see improvements in a number of measures of health if he did just three minutes of HIT a week, for four weeks.
Simple Program The HIT program he asked Mosley to follow was quite simple and can be done on a standard exercise bike: First, you warm up for a couple of minutes with some gentle cycling: Then, you cycle gently again for a couple of minutes while you catch your breath, then do another 20 seconds "flat out".
Then, for a final time, two minutes gentle cycling to catch your breath, followed the third period of 20 seconds at "full throttle". Do this HIT program three times a week, and you have a total of 3 minutes a week of intensive pedalling, and about 6 minutes of gentle pedalling.
Mosley said he was somewhat sceptical, but he did as Timmons instructed: Insulin Sensitivity Timmons had tested Mosley for a number of health indices before he started, and then, after his 4 weeks of HIT, Mosley went back to the lab to be re-tested.
A main test was for insulin sensitivity. Mosley was particularly keen to see this result as his father had been a diabetic and had died from complications linked to the disease.
When they measured Mosley's insulin sensitivity before he started his HIT exercise regime, the result showed he was just inside what would be regarded as healthy tolerance. And this is exactly the amount by which Mosley's own index improved. But bigger improvements than this have also been recorded, albeit with a slightly different HIT regime.
Their biking regime was 10 times second bursts of intense pedalling with 60 seconds of recovery time in between each, performed three times a week the whole workout, including 3 minutes of warm-up and 5 minutes of cool -down, lasting less than half an hour.
Insulin sensitivity is important for keeping blood sugar or glucose stable. When you eat, your digestion starts putting glucose into your bloodstream.
This causes the pancreas to release insulin, a hormone that triggers body tissue to absorb circulating glucose. If your insulin sensitivity reduces, the pancreas has to release more and more insulin to keep blood glucose levels stable.
Abnormally low insulin sensitivity is known as insulin resistancea condition that results in high levels of insulin, glucose and fats circulating in the bloodstream. It is a main risk factor for metabolic syndrome, which increases the risk for coronary artery disease, strokeand type 2 diabetes.
It is not clear how HIT affects insulin sensitivity, but Timmons, and some other scientists that Mosley spoke to, suggest it could be because HIT uses many more muscles than conventional aerobic training.
HIT engages not only leg muscles, but also the muscles in the upper body, such as the arms and shoulders. One of the effects of exercise is to break down glycogen in muscles. Glycogen is a stored form of glucose.Starting an Exercise Program with Fibromyalgia.

Clinical and epidemiological studies have demonstrated that regular aerobic exercise reduces the risk of death due to heart disease and stroke, aids in reducing weight, helps prevent diabetes mellitus, strengthens bones, and enhances immune function. Weight-loss benefits Aerobic exercise burns up calories, which can in turn help you shed excess weight, Jonesco says.
Aerobic exercise also tones your muscles and improves posture.
