Resting heart rate
To measure your resting heart rate, you can either use a heart-rate monitor and sit quietly for 10 minutes, and use the lowest pulse measurement you get, or you can simply sit quietly for 10 minutes, then measure your pulse by counting it for 30 seconds, and multiplying by 2.
Waistline
To measure your waistline, use a measuring tape around your middle at the level of your navel.
