Yoga can increase height by up to 1 inch, reports Esquire. The ancient practice works by lengthening the spine and improving posture. Practicing yoga two to three times per week can lead to measurable results, but no exercise can change a person's basic bone structure or genetic disposition.
Height is determined by a combination of genetics and environment, according to The Tech Museum of Innovation. Every individual is born with the potential to achieve a predetermined maximum height. Regular exercise and proper nutrition are necessary for bones to grow to their full length. Exercise also stimulates production of testosterone and growth hormone, which both contribute to height.
