Strength training helps your body trade fat for muscle mass. That means you’ll burn more calories even when you’re being a couch potato. But these workouts can also help you slim down, strengthen your heart, and build up your bones. Do strength-training exercises — like push-ups, lunges, and weight lifting — at least twice a week.
A few minutes in the sunshine raises vitamin D levels, and that’s good for your bones, your heart, and your mood. Plus, being outside means you’re more likely to move your body instead of parking it in front of the TV or computer. Choose nature over city streets, if you can. One study found that people who strolled in urban green spaces were calmer than people who walked in built-up areas.
