The heart is your life and your soul. You can not exist without it beating. It is made up of muscle around the size of your fist, divided into four chambers that pump approximately 110 million gallons of
blood in a lifetime and, if looked after, will last around 80 years, with very little attention given to it. It is a truly amazing little thing that for most of the time we pay very little attention to. Then one day we go and have a blood pressure check and it says something we don't expect..and off we go with cholesterol checks, questions about your diet, how much you exercise.
Your
heart is a muscle, it likes to be worked. That means you need to get out of breath (but still be able to talk [but not easily]). You should feel uncomfortable at times, but then slow down so you get back to the breathing a bit quicker but can talk again. You should perspire when you exercise - it means you have an efficient cooling system and you are working hard enough for your body to want to cool you down a bit.
We have a blood pressure cuff for anyone who might want to check theirs but doesn't want to go to the doctors. make sure you book and come early enough so you can have a sit on the sofa for 5 minutes before we take it...and not just after you have jogged here. It takes longer than that :D
