This is a lot of common sense, however, to my surprise, I still see people mistreat their bodies.  As we age, there are smart adaptations to consider while embarking on your healthy lifestyle plan.

 In general, it is advisable to have a proper warm-up and cool-down and avoid any quick changes in position.  This helps to prevent injury.  We must do our best to keep our knees and feet healthy!

Aim to breathe normally and use perceived exertion to evaluate your intensity.  When we have a cold, are in higher humidity and heat temperatures, or at a higher altitude, the body will have to work harder, therefore this must be considered.   

Ideally, aim to exercise 3 to 5 days a week for a minimum of 20 minutes.  I do not believe in going over 60 minutes unless very fit.  The ideal time is 30-45 minutes.  

If raising your HDL levels is the most important goal of your plan, it is recommended to exercise 3-4 days per week at 30-40 minutes at 65 to 85 percent Max HR.

Try to find something you love to do.  I walk in nature or do dance cardio because I love music.  Many enjoy stationary biking in front of the television or going for a swim.  The important thing is to be consistent and listen to your body.
