Medical studies have shown that exercising for less than 15 minutes will not burn any more calories than normal everyday activities. In other words, if you want to lose weight, how long you should exercise for is very important. Exercising for less than 15 minutes is next to useless, but you still get some advantage in that you have at least used your muscles and moved, which is better than watching television.
To get the most out of exercise you should carry out the activity for at least 30 minutes each day. This then burns more calories for the second 15 minutes.
Couple a walking program with muscle toning and you can eventually burn more calories per exercise session. For every gram of muscle that you build you will burn 90 calories per hour more, that's a great way to lose more weight in the long term.
So it's beneficial to introduce slowly building muscle tone while undertaking a walking program. Both will help increase the burning of unused calories and couple that with sensibly eating patterns and counting calories, you will soon be looking great and feeling if you could conquer the world.
So how long should you exercise each day? Aim for at least 30 minutes daily and you will see a regular weight loss when you also combine sensible eating patterns.
