When attempting to change your body shape in any way its important to track your progress so you can see results as they happen, this will give your motivation a huge boost and will also show that your efforts are not being wasted.
To get a true gauge of progress you should take measurements from 4 areas of the body, these are your chest, arms, thighs and waist. You will need to get a friend or partner to help you with the measurements, as some will be very tricky to do on your own, it will also make them more accurate.
Ideally measurements will be taken now, so you have a clear starting point, then you should take the measurements on a regular basis, I would recommend doing them on a fortnightly or monthly basis, some of you will be tempted to do them weekly or even daily, I would advise against this as you won’t see changes on a daily or even weekly basis and this will only upset you.
If you do measure on a monthly basis, do them on the same day and time each month, e.g. 3rd of the month at 10:00am.
