Sticking to a new fitness routine can be tough and sometimes you may be tempted to skip your workouts. While that’s completely normal, it can help you stay on track if you can easily remind yourself why you wanted to get in shape in the first place. Maybe you want to be able to keep up with your kids without getting out of breath, or perhaps you want to lower your cholesterol. Whatever it is that motivates you, write it down somewhere safe—like your phone. This way you can refer back to it when you need some extra motivation.
As you get started toward the recommended 30 minutes of moderately intense aerobic exercise five days per week, aim to exercise at a level that just lets you keep up a conversation during the activity. If you can get out three or four sentences in a row without gasping for air, it’s a sign that you’re maintaining an intensity that is truly aerobic, meaning aerobic metabolism is supplying the vast majority of your body’s energy, Jonesco says.
A brilliant book at all levels, Walking for Fitness is written by Nina Barough who started the Walk the Walk charity and is a power-walking guru. It covers absolutely everything, with sections on how to get started, basic walking technique, stretches and complimentary exercises, good walking shoes and clothing, cross training, food intake, related injuries, walking with children, walking while pregnant, walking for charities or in competitions and training programmes.
Physical therapist, Col. Pauline Potts and Dr. Kenneth Cooper, both of the United States Air Force, advocated the concept of aerobic exercise. In the 1960s, Cooper started research into preventive medicine. He conducted the first extensive research on aerobic exercise on over 5,000 U.S. Air Force personnel after becoming intrigued by the belief that exercise can preserve one's health. Cooper published his ideas in a 1968 book titled, "Aerobics". In 1970, he created his own institute (the Cooper Institute) for non-profit research and education devoted to preventive medicine and published a mass-market version of his book "The New Aerobics" in 1979. Cooper encouraged millions into becoming active and is now known as the "father of aerobics". Aerobics developed as an exercise form in the 1970s and became popular worldwide in the 1980s after the release of Jane Fonda's exercise videos in 1982.
Update: the authors removed a sentence about the human body operating on physiology rather than physics. This sentence was in reference to 500kcal exercise not directly relating to the number of grams in 500kcal of fat as determined by typical bomb calorimetry. This is due to the various ways individual physiology treats energy intake and energy expenditure. The authors decided to remove the sentence since it lacked the additional context behind the statement.
If it’s too hot to walk or run, swimming can be a cool way to get fit. It’s a low-cost workout for the whole body especially the muscles of the back, shoulder and arms and improves flexibility as well. It’s a good way to exercise if you’re overweight, pregnant or have joint problems as the water helps support your weight and can reduce the pressure on your joints. The risk of injury to muscles, ligaments or joints is also low.
