While walking is beneficial for overall health, a targeted approach is essential for tightening your thigh skin. Engaging in a resistance training program or starting exercise routines such as Wall Pilates or HIIT workouts can target the thigh area. Scientifically, studies have shown that targeted exercises are essential for comprehensive skin tightening. Non-surgical methods, including collagen-boosting foods and hydration, complement exercise routines for holistic thigh skin tightening.
