Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. Plus, it'll help you relax post-meal so you won't be tempted by stress-induced grazing that can rack up calories.
It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement.
In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
