Most of us hate the scale, but it is a necessary tool for many. Hop on the scale, write down your weight and record it once every week or every month.
Do not weigh yourself every day. If you don't want to know your number, have someone else record it for you, like your significant other or a trusted friend.
Also take measurements. Measure your arm (around the bicep), your neck, your chest, your waist, your hips and your thigh. Some weeks, the scale will not move but the inches will. Take new measurements every six to eight weeks.
Do not let the occasional weight gain or no-loss weeks get you down. Use these weeks as motivation. What can you do differently? Can you add another workout? Did you overeat? Assess and move on.
