What do I need to know before I get started?

Please speak to your doctor before starting any new exercise program.

Is there anything I need to do when I exercise?

Remember to start slow. Aim to exercise only one to two days a week until you get into a routine. The goal is for you to be able to exercise following the guidelines below.

Your energy levels will be different week to week. So if you do not meet your exercise goal one week, it is ok! You can always make up for it the next week.

When you exercise, make sure you warm up before you start. You can do this by going for a fast five minute walk that starts to raise your heart rate. Make sure you cool down after you exercise as well. You can do this by going for a slow five minute walk to bring your heart rate back down.

If you want to make sure you stick to your exercise routine, it is important to choose an activity that you enjoy and will continue to do!
