How to achieve privacy and compactness?

Do more exercise at ordinary times, such as: stand up and contract, stand with your legs apart, contract the muscles on both sides of your hips, make them hug each other, form thighs together, turn your knees outward, and then contract your sphincter to move your private parts upward.
