Hips: Place the measuring tape across the widest part of your hips/buttocks and measure all the way around. Pretty much the roundest peak of your butt.
Chest: Place the measuring tape just under your breasts/pecs and measure around the torso.
Right and Left Legs (Thighs): Measure around the largest part of both thighs. About upper/mid-thigh. Leg
Right and Left Arms: Measure around the largest part of each arm (biceps), above the elbow. Measure the same portion of the arm every time.
