There is a common misconception that you should get all of your cardio for the day done at one time. However, if you are strapped for time, and can not squeeze in 45 minutes in one workout, break it up into smaller sessions. Experts recommend that you get 30 to 60 minutes of exercise, five to seven times per week. If your schedule is hectic, and you can only fit in 10 minutes three times a day, take advantage of those 10 minutes. That is one of the reasons why
Tony Horton created the
10 minute trainer.
To make the most of the time that you have, try interval training. Go for one minute at high intensity then switch to one minute of low intensity. This type of training has actually been proven to burn more calories than medium intensity routines. It also builds endurance, and gets your metabolism going.
As with any other
fitness routine, you should always warm up before beginning your interval workout. This method of training can be done on a variety of machines, as well as using a wide range of aerobic activities.
An example of running, using interval training would be; warm up, run at a fast pace for one minute and then walk for one minute. Repeat this routine, until your time is up. This type of training is implemented in 'Boot Camp' as a way to get their soldiers in shape as fast as possible.
You could also interval train by jumping rope, kick boxing, running up a flight of stairs and walking back down; you imagination really is the limit.
You can also incorporate weight training into your intervals. By joining the two you get your cardio, while toning those trouble spots. Try adding push ups and sit ups to your intervals. Another element that can add to your interval training is dance.
Get creative, and do what feels good for you. After all, if you enjoy the routine you are more likely to stick to it. When you find yourself becoming bored with your routine, switch it up and try a new one.
