Facultative and Microaerophile aerobes: Facultative bacteria behave both aerobically and anaerobically, according to the prevailing conditions. In reduced environments, they acquire energy via anaerobic pathways, whereas in oxidative environments, they develop aerobic pathways. The microaerophilic bacteria require oxygen but in very low concentrations.
Classes are great for people who like to exercise with others, who like to dance, who like music and rhythm, who want the extra motivation and energy that an instructor and class provides, and who prefer the structure and schedule of a regular class. Classes, equipment, and videos are all great ways to stay fit and healthy, but if you're limited by injury or other conditions, then aerobic exercise chair workouts may be just the thing (see resources for online vendors). The instructor leads you through a workout in a chair and it's great exercise. You might not need chair exercise, but you may have a parent or friend who does. Exercise videos and DVDs make great gifts!
Walking can also help lower blood pressure. Researchers from Wakayama Medical College, Japan conducted an experiment on individuals with mild hypertension, where 83 participants walked 10,000 steps per day for 12 weeks. At the end of 12 weeks, they showed a significant drop in blood pressure and increased stamina (5). Even if you are unable to complete 10,000 steps per day, you should walk for at least 60 minutes every day to keep your blood pressure levels in check.
