Introverted
Just because you like spending time on your own doing quiet activities, doesn’t mean you have to miss out on fitness.  If thinking about the gym brings on feelings of dread for you, stay home instead.  Invest in some exercise machines to build your own personal gym.  That way, you can work out in privacy and better focus on your objectives.

A cheaper alternative is to get some fitness books or magazines.  These sometimes set up a routine of poses or exercises you can do in addition to your cardio.  It’s way easier to follow a workout someone else has set up than to have to make one up by yourself. 

Stay-At-Homes
Plenty of people work at home, and if you’re one of them, you know it can be hard to fit an exercise routine into your schedule.  Working at home often means you don’t have set hours or guaranteed time off.  When you do have time to exercise, the workout needs to be quick and planned out in advance.  A great solution is to use workout DVDs. 

You can get DVDs that focus on cardio, weight training, yoga, Tai Chi and much more.  These videos give you the luxury of pausing and picking up where you left off whenever you have more time.  Best of all, these workouts are all set up for you, so you don’t have to do any guesswork. 

Economical
Fitness can get expensive.  You might want the results of going to a gym or using a fitness video, but it's natural to not want to spend a ton of money.  Get creative and look at what you already have or already do that can count toward your fitness goals.  Do you do housework?  Chores like vacuuming or scrubbing the bathroom tub force you to use several different muscles at once.  What about using household items as workout aides?  If you have any cans in your kitchen cupboards, use them as weights.  Do things that use what you have and don’t require extra cash.  Better yet, go for a walk or run outside -- that’s free.

A Customized Routine
When it comes to getting fit, do what feels natural.  That way, you won’t feel like you’re going out of your way to keep healthy.  When you find out what type of personality you have, you can pick a plan that’s best for you.
