Thighs are the upper part of your legs, located between your hips and knees. They are made up of strong muscles that help you walk, run, and jump. The main muscles in the thighs are the quadriceps, which are at the front, and the hamstrings, which are at the back. These muscles work together to support your movements and keep you balanced. In addition to muscles, thighs also contain fat and skin, which help protect the muscles and bones underneath. Many people focus on their thighs during exercise, using activities like squats and lunges to strengthen and tone this area. Healthy thighs contribute to overall fitness and mobility.
