Pilates can be beneficial for toning and strengthening the muscles under your skin. This gives the appearance of tighter and firmer skin. Core exercises in Pilates, such as the Plank, the Hundred, and the Roll-Up, target the deep abdominal and glute muscles.
While Pilates may help tone and firm certain parts of your body, the practice alone may not be enough to tighten loose skin significantly. Your skin’s elasticity depends on many factors like age and genetics.
