How much exercise should you do?
Choose what you’ll do and make detailed plans. Think about what activities are realistic for you and choose the ones you think you can do. Start slowly. Your activity should be somewhat challenging but not overly difficult. Write down exactly what you’ll do, where and when you’ll do it, how often, and for how long. Allow yourself to get into a routine. Be flexible and don’t get discouraged. For example, I’ll get off the bus one stop earlier. Don’t be too hard on yourself if you can’t. For example, if it’s raining, you may not want to walk outside so you can choose a different activity. It’s more important to reach your long-term goal than to follow the plan from day to day. Plan how you’ll reward yourself for your efforts. For example, some people treat themselves to a movie when they meet their goal for the week.
For minimum 30 minutes and 5 times a week. Do it regularly and increase it as per your body's capacity. Start and end your exercise gradually Increase the intensity and duration of your exercise program gradually. Start at a minimum (good warm up & end with cool down phase-walk with relax pace for 5 min & stretch down arm & legs for 5 min) and build up your stamina gradually over days before going in for your full capacity to achieve the target heart rate. (Health experts recommend exercising 30 min daily to maintain your current weight and 45 to 60 min of daily exercise if your goal is to lose weight. At first, keep your exercise sessions short. Don’t overdo it when you exercise. When exercising you should be able to carry on a conversation without getting out of breath).
The housewives argue that they work whole day in their house so they don't require additional exercise. It is true that they are busy whole day but not getting proper exercise. There fore, they must at least 30 minutes and go out of their home for walking or do any other exercise.
Remember
If you experience over strain, sweating, giddiness, and chest pain or short of breath, just stop the exercise and take doctor's advice immediately.
