Hips can be made wider with proper exercise and weight training. Hips are not only bone, they are made up of muscles from the gluteus minimus, maximus and medius. Working on building these muscles helps to increase the size of not only the rear end, but the hips as well.
In ancient society, wider hips were a sign of a healthy child bearing woman. The visual appeal of wide hips has not lost its popularity in modern times, as they give curves to the female form.
Genetics do play a role in how wide hips can become; however, with weight bearing exercises that focus on hips, thighs and glutes, curvy, wide hips are a possibility.
Working the muscles that surround the hips at different angles is key to making substantial gains. Find the right weight for the exercises so you do not injure yourself. Start with different variations of lower body exercises, such as squats, lunges, straight leg dead lifts and lying leg lifts. Include yoga and stretching several times a week to increase flexibility and to widen the hips with certain poses.
Incorporate a healthy eating program with the right balance of proteins, carbohydrates and fats to fuel the body. Expect visible results within six months to a year of consistent exercise and healthy eating.
