After you choose what to do, the most important element of your workout will now be how long you do it. You should work on duration before you work on anything else--it's more important than how fast you're going. If you're a beginner, be cautious and start with a few minutes, adding more time to each workout until you're up to 30 minutes.

The 'official' guidelines say to workout for an hour. Once you've stopped laughing over the idea of finding an hour for exercise, listen up: if you don't have that kind of time, use whatever time you DO have, even if you have to:

  • Do mini-workouts throughout the day
  • Take a few minutes here and there for some stair-climbing or speed walking
  • Do all those things you know you should be doing: take the stairs, walk more, stop driving around looking for that primo parking space, etc.
  • Make the time. People who workout don't have more time than people who don't. They're just better than you. Kidding! No, regular exercisers have learned how to prioritize their time and make exercise number one on their to-do list. Plus, they know it makes life better (something you'll find out for yourself, little grasshopper).
  • Pay someone to make you exercise. Finding a good personal trainer can make a difference when it comes to motivation, goal-reaching, etc. You can even hire someone online.
  • Do something...anything. If you think 5 minutes isn't enough time to workout, you couldn't be more wrong. 5 minutes, 10 minutes, 40 minutes--every single minute counts so don't flake out on me with the I've-only-go-a-few-minutes excuse because I'm not buying it and you shouldn't either.

Note: doing too much cardio is a no-no as well. You don't need to kill yourself with hours of cardio--there is a point of diminishing returns, so keep it reasonable and don't forget to take some rest days.
