It is a matter of prioritization. Are YOU high on your list of priorities? Is your health? You must make yourself a priority to get in that regular workout.

Try to structure your schedule to allow exercise. Maybe the fitness club is the wrong approach. Could you participate in sports of some sort?

Doesn’t have to be done every day. But you need to make time for it. Surely you have some days off. What about those days?

First, let’s talk about taller. That’s genetics and nothing you do will help you get any taller than you’re predisposed to be. The best predictor for height (for a woman) is to take your father’s height and subtract five inches, then average your parent’s heights together. I’ll put an example at the end.

Now, let’s get to the better body shape. Anything you described will help you lose weight and look better. If you’d like to target specific areas of the body, the gym would be ideal. If you’d like to improve cardio you could add running, soccer or even tennis to your reportoire. The best thing to do is to vary your routine. You need to give your muscles a rest, so you shouldn’t run every day… BUT you can run one day and work your abs or upper body the next (if you’d like to workout on a daily basis). By strengthening your muscles you begin to give yourself a more defined body which creates a good body shape.

Good luck!

Example of height predictor… I’m 5′4” and my husband is 5′10”. Let’s say we have a daughter. You take his height and subtract five inches, which makes it 5′5”. Then you take my height (5′4”) and average it with 5′5", making my daughter’s geneticly predicted height 5′ 4.5”. Obviously this isn’t perfect, but it is the best predictor based on shared genetics we have. I think the statistics state there is a 68% chance you will be within 2 inches of this height and 95% that you’ll be within 4 inches.
