ALWAYS obtain permission from your doctor BEFORE participating in an exercise regime of any kind.
When partaking in physical activity and exercise do so in a SAFE environment. START SLOWLY and listen to your body! Do what YOU are capable of. Take particular notice of your heart rate, breathing, and how tired your muscles get. If you get short of breath or very tired, rest, and start again as you are able. To help with motivation and gain added benefits, do activities/exercise with some company.
