As a former athlete, this manageable mantra helped keep Kit from burning out on her workouts when she was trying to lose weight. “I come from a background of injury, and I had knee surgery, so you can’t tell me to go and take some crazy bootcamp class,” she says. “Because my knee will start to hurt, and then what’s going to start to happen, I’m going to freak out that I won’t be able to do that for the rest of my life.” Instead, just telling yourself to do something little every day can help you get a hold of your health and your weight-loss goals. “Women need to feel empowered,” she says. “They need to feel like what they’re doing is something that they somewhat enjoy and that they can have a grip on. And that’s why I believe in this three or 30 rule.”
