Achieving the much-coveted trim waist or six-pack is a common goal for many bodybuilders. Quite possibly, this is a goal of yours. If so, then in your pursuit of this goal, you’ve probably asked yourself: “What is my ideal waist size”? Well, there is no precise method to determine your ideal waist size, as there are so many variables. However, there are methods you can use to get “rough” estimates of your “ideal” waist size. I have a method for men and another method for women:

For Men – Shoulder to Waist Size Ratio Method and Chest to Waist Size Ratio Method – By measuring your shoulder circumference and/or chest circumference, you can calculate an “ideal” waist circumference. These proportions have been determined by scientific studies that revealed which dimensions of the male girth are most attractive to women. The masculine “V-Taper” look with a shoulder-to-waist ratio of 1.6 and a chest-to-waist ratio of 1.4 are the most desired and pleasing proportions for women.

To calculate the ratio of shoulder to waist size, measure the circumference of the shoulder and divide that number by 1.6. For example, if you had a shoulder circumference of 50″, divide 50 by 1.6 to get an “ideal” waist circumference of 31.25″.

For the calculation of the ratio between the size of the chest and the waist, measure the circumference of the chest and divide it by 1.4. If I had a chest circumference of 44″, then I would calculate an “ideal” waist size of 31.4″.

For women: waist-to-hip ratio– Studies of female shapes have been conducted to determine the waist-to-hip ratio that men find most desirable and attractive. According to these studies, the “ideal” waist circumference for women is 0.7 hip circumference.

To find your “ideal” waist size, measure your hip circumference at the fullest part of your hips and multiply that number by 0.7. For example, if your hip circumference were 36″, then your “ideal” waist circumference would be 36″ x 0.7 = 25.2″.

Waist size can be set as a goal. Use these estimated “ideal” waist circumferences as guidelines when setting your abdominal training goals. Your waist size goal will help you determine your progress toward reaching your six-pack goal.
