“As your body’s perception of stress increases, cortisol, often called the stress hormone, is released from the adrenal glands,” explains Nana Yaw Adu-Sarkodie, MD, a board-certified family physician practicing home-based care in Baltimore. “Normal levels are released when you wake up in the morning or during exercise. Chronic stress can lead to increased cortisol and other stress hormones, leading to increases in sugar in the bloodstream, weight gain, digestive issues, depression, and a host of other health effects.”
Plus, lifting weights in and of itself burns calories. So while you're pumping through your reps and breaking a sweat, your body is burning calories. You just need to make sure you are lifting weights that are heavy enough to be a challenge but doable to make it through full sets; if you're not sure where to start, check out this guide. After a weight starts to become too easy, it's time to lift heavier or increase reps to continue to see progress; this is known as progressive overload.
“[These tools’] potential benefit is awareness,” Fear says. “Knowledge can be power, but these things can be counterproductive when they simply create alarm without any clear course of action to take. Seeing your weight rise doesn't necessarily provide you with any action steps you can take. It's just upsetting, like a fire alarm going off with no exit routes identified.” Langer notes that “in people who have a history of or are at risk for an eating disorder or compulsiveness, tracking anything should be off limits.”
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."
