Just as you record how your body measurements change, I’d also like you to record how your fitness improves. This can be done very simply, by walking a set distance as fast as you can and recording the time it takes you and your heart rate. You will need to do this test at the very start of the plan and also on day 28. You will surprised at how much your body can improve in just 28 days.

On my 28-day programme we walk as fast as we can for one kilometre. If you are a complete novice to fast walking and exercise I suggest you complete a timed walk for half a kilometre. Your route should be as flat as possible. The route I use is beside a park. One length of the park is 250 metres, so we walk the length of the park four times to complete a kilometre as fast as we can.

Before you start your timed walk, record your heart rate for one minute. This can be taken at your wrist or your neck. Take your heart rate for one minute immediately after completing the walk, and then again after one minute of recovery. Record your heart rate results and the time it took you to walk on the chart below. Take a piece of paper and a pencil with you to jot down your results, and fill in the chart when you get back home.

HOW TO TAKE YOUR HEART RATE

You can take your pulse either at your wrist (radial pulse) or at the side of your neck (carotid pulse). You can feel your radial pulse by tracing a line down from the base of the thumb. Place the tips of your index and middle fingers over the artery and apply light pressure.

Some people find it difficult to locate their radial pulse. Your exercise pulse, in particular, is much easier to locate at the carotid artery, to the side of the larynx. Do not apply heavy pressure to the carotid arteries because they contain baroreceptors that sense increases in pressure and can slow the heart rate.

Another very accurate and easy method of measuring your heart rate is with a portable heart monitor. There are a number of these on the market and they consist of a chest strap with electrodes that pick up the electrical activity of your heart. These are generally a lot more accurate as they are picking up your actual heart rate as opposed to your pulse.
