Lift weights and strength train to add muscle and tone to saggy skin on the legs. This will tone the muscles in the thighs, the hamstrings and the calves in order to build the muscle back up.
Maintain a low-fat diet. Consuming less saturated fats and processed foods can reduce excess fat, which can lead to saggy skin. Food such as cucumbers, coconuts and olives have properties that help improve the skin’s elasticity.
Drink water to stay hydrated. A hydrated body helps the leg muscles rebuild more efficiently. Drink at least eight glasses of water a day. Eat such water-rich foods as fruits and vegetables.
Individuals who maintain weight loss through vigorous exercise can over train the body and lose too much muscle, which can lead to saggy skin. Replenish essential minerals needed for muscle development with sport drinks containing electrolytes.
Take a multivitamin high in magnesium. Magnesium supports muscle development and improves skin elasticity.
Wash your legs with a loofah scrub daily to exfoliate and tighten loose skin. Always moisturize after with an aloe vera-based lotion to replenish and trap in the skin's moisture. Use lotions that prevent further loose skin; products with aloe vera and hyaluronic acid--a component naturally found in the body's tissue--can work together to lubricate and tighten the skin.
Consider plastic surgery to remove excess sagging skin. Diet and exercise may moderately reduce loose skin after sudden weight loss or pregnancy, but surgery can fully remove skin that cannot be tightened. For moderate loose skin, skin wrapping may be an effective alternative to shrink loose skin.
