Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to exercise your abs standing up [title] Use twisting exercises to work your obliques. [step] Ab exercises that include a twist or cross component will work your entire core, but are especially helpful at working the obliques that run along the sides of your abs. [substeps] For example, you can try side-to-side waist twists.

Ending1: If you work the obliques under your ribs, doing side-to-side circling movements can help you work your obliques. You can throw your abdominal muscles over the top of your head and bow over a bit to get a good twist or weight while doing this exercise. Ending2: To do a side-to-side side twist, tighten your abs. To do a cross component, make several twists and lengthen your abs. Ending3: Hold your arms close to your body with your elbows bent. Slowly turn your shoulders to the right while keeping your hips forward. Ending4: These will help relieve your obliques symptoms, which will gradually widen. Also try doing butterfly twists or quadriceps extensions-although the technique is much more painful.
