"It's important to give ourselves grace and not beat ourselves up," she told Us Weekly. "For so many years in my early 20s, I was all or nothing. I have the best relationship I've ever had with food and health because I've let go of a lot of that control. It's about consistency — just keep showing up." "It's tempting to buy into promises of rapid and dramatic weight loss, but a slow and steady approach is easier to maintain and usually beats fast weight loss for the long term. A weight loss of 0.5 to 2 pounds (0.2 to 0.9 kilograms) a week is the typical recommendation," says the Mayo Clinic.

"Like everyone else, my workout and health routine has been up and down during quarantine, but I finally have gotten back on track," she told Us Weekly. "I lift weights, but I do circuit training to keep my heart rate up. I also started doing hot yoga every once in a while. I don't do it as often as I would like, but I love it when I'm able to make it happen."

Hot yoga works. Just be sure to stay hydrated. "Adequate hydration is clearly a critical factor in preventing the adverse effects associated with exercising when the temperature and/or humidity are high inside the yoga studio. In this situation, the ideal approach is to take appropriate steps to prevent dehydration during the workout. To achieve this objective, participants should be encouraged to undertake the following steps to ensure that they are well hydrated before participating in a hot yoga class," says ACE Fitness.

"It's not as complicated as you might think. Interval training is simply alternating short bursts (about 30 seconds) of intense activity with longer intervals (about 1 to 2 minutes) of less intense activity," says the Mayo Clinic. "For instance, if your exercise is walking and you're in good shape, you might add short bursts of jogging into your regular brisk walks. If you're less fit, you might alternate leisurely walking with periods of faster walking. For example, if you're walking outdoors, you could walk faster between certain mailboxes, trees or other landmarks."

"Mon-Fri I wake up at 5am to workout before my kids wake up. I love that quiet time to myself before the craziness of the day starts," she told Glamour. "I lift weights 5 times per week and I eat real food. I never look at calories, only the ingredient label. If there are crazy additives in it, I stay away. When I'm cooking at home, I cook gluten free and I never use cow's milk. When I'm on vacation or go out to eat I'll allow myself those things…all about balance!"
