Every session of aerobic exercise should include a warm-up and cool-down. The warm-up period should not include static stretching, but should instead be a gradual increase in pace and intensity of the exercise. This allows for the body to increase blood flow to the muscles, and decreases the likelihood of a muscle or joint injury. The warm-up should last between 5 and 10 minutes. The cool-down session should last a similar amount of time as the warm-up, with the pace gradually decreasing. Stretching exercises would be appropriate after aerobic exercise.
For weight loss, gradually work up to 45 minutes or longer at moderate to vigorous intensity five to six days a week, allowing for at least one day of rest a week. Vigorous intensity refers to an activity that will have your heart beating quite a bit more than moderate intensity workouts, and your breathing will be harder so saying more than a few words will be difficult.
For joints to work at their best, you need to keep them moving. Regular walking gives knee joints a workout, increases your muscle strength and can keep your bones strong, giving definition to calves, quads, hamstrings and lifting your glutes. Walking not only stimulates and strengthens bones, increases their density and helps maintain healthy joints, it can also fend off conditions such as arthritis and help prevent or alleviate back pain.
There ins and outs of different methods of measuring your walking speed. Cell phone apps and running speedometer watches use GPS, which can be inaccurate and won't work indoors on a treadmill. Fitness bands and pedometers may use your step cadence, which can vary if your stride length is different from what is expected. You can verify the accuracy of these readings by walking a measured mile and calculating your walking speed and pace.
Do you suffer from joint pain, heart problems, stress, depression, or obesity? Then, try walking to beat all your health problems. Because according to the journal Medicine and Science in Sports and Exercise, walking helps reduce the risk of chronic diseases (1). In fact, most health professionals prefer walking over running as it is a low-impact exercise that goes easy on your heart and joints. Read on find out about the 20 health benefits of walking daily and get going, doesn’t matter if you are 8 or 80!
I walked along my bus route, assuming that sooner or later, my arrival at another bus stop would coincide with the arrival of my bus. But it didn’t. So I walked some more, eventually making it to work, a mere 20 minutes later than I normally would have, calmer than I might have anticipated, and feeling like I’d accomplished something vaguely mammoth before 10am. I also felt liberated. Who wants to be enslaved to their public transport systems, beholden to the schedules, the whims and capriciousness. Suddenly, I had another option.
1. Walk as much as you can. The University of Warwick study compared people with at least one sign of metabolic syndrome—a group of risk factors (high blood pressure, fat around the waist, high blood sugar, and high triglycerides and cholesterol) for heart disease—to those with no risk factors. They found that those who got the least activity had the most risk factors, and those who walked the most—accumulating at least 15,000 steps per day—had healthy BMIs, smaller waists, lower cholesterol and blood pressure, and better blood sugar control.
Though the risks of being sedentary far outweigh the risks of exercise, one should be prudent when beginning an aerobic exercise program. Safety guidelines from the ACSM state that individuals at low or moderate health risk can begin a moderate-intensity exercise plan without a medical exam or exercise stress test, whereas people at high risk should be evaluated by their doctor. You are at high risk if you have:
The American Heart Association recommends that everyone reach a minimum of 30 minutes of some form of cardiovascular exercise 5 to 7 days per week. This can be broken up into 10-minute time periods. This means that taking 3 walks of 10 minutes each would let you reach the recommended minimum guideline for reducing the risk of heart disease, diabetes, hypertension, and high cholesterol. You would also burn the same number of calories as you would if you walked for the full 30 minutes at 1 time.
A single activity can include elements of both aerobic and anaerobic exercise. For example, interval training, where you alternate cycles of low-intensity (aerobic) and high-intensity (anaerobic) work during the same workout, has elements of both. So does a game of tennis where you might sprint at one moment (anaerobic) and then move less aggressively for several minutes (aerobic) as you hit ground strokes from the baseline.
When bones thin too much – a disease called osteoporosis – you become more susceptible to fractures. In young people, whose bones remodel and rebuild with ease, this might not be too concerning. However, if you are an older individual or have compromised bone density, fractures can significantly affect quality of life and impact your ability to perform the daily activities you need to remain independent.
