4. You Pretend to Be Allergic to Dumbbells
Following a regular strength-training routine that creates better, more supportive muscle tone will help you firm sagging skin from the neck down. "I am religious about strength-training, and I always tell patients to do it more as they get older," says Patricia Farris, MD, a dermatologist in Metairie, LA. "It's like adding volume to the face with fillers, except on your body," says Dr. Farris.
5. Your Meat and Dairy Aren't Organic
"Hormones in traditionally produced dairy, poultry, and meat may contribute to acne," says Katie Rodan, MD, a dermatologist in the San Francisco Bay area. She says that her patients who eat those less frequently—or at least choose grain-fed beef and poultry and organic dairy—often notice their skin looks better.
6. You Don't Give Your Body a Break
When your exercise routine is so intense that you're tired all the time but can't sleep at night, you're setting yourself up for overuse injuries—not to mention dark circles and bags under your eyes from those sleepless nights. These symptoms could be a sign of overexhaustion, says Ryan Halvorson, personal trainer, IDEA Health and Fitness Association expert, and author. Other clues that you're working out too much include extreme muscle soreness that persists for several days, unintended weight loss, an increased resting heart rate, interruptions in your menstrual cycle, or decreased appetite. "Plan your rest as well as you plan exercise," says Polly de Mille, RN, a registered clinical exercise physiologist at the Hospital for Special Surgery in Manhattan. "If there is no balance between breakdown and recovery, then the muscle is in a state of chronic inflammation and what may start as a simple case of soreness after a hard workout can turn into an actual overuse injury."
