1. You think just walking is good enough
Walking is certainly helpful when you’re trying to lose weight and get in shape, but just walking isn’t enough.
Adding 30 minutes of brisk walking to your daily routine can help you burn about 150 extra calories a day. Although this is no doubt beneficial, you generally need to eliminate about 500 calories a day to lose one pound per week.
Naturally, the more you walk and the quicker your pace, the more calories you’ll burn. The longer you exercise, and the more intense your workout, the more calories you burn. It’s important not to overdo it; over-exercising can lead to injury, soreness, and burnout, hindering your long-term goals. However, you should gradually build the intensity of your workouts. If you’re sedentary and out-of-shape, it’s fine to start out with walking and gradually exert yourself more.
With all of that being said, you should never "replace" walking with other workouts. To truly have a healthy lifestyle and maintain weight loss. You need to MOVE. Sitting for long periods of time (and by "long", we mean only a half-hour) is detrimental to your health and can even lead to heart disease. The damage done to your body by sitting cannot be undone, no matter how hard you work at the gym afterward. So, every half hour, just get up and move around.
When it comes to losing weight, exercise is just part of the equation. There’s no doubt working out is important, but eating a healthy diet is also important if you’re trying to lose weight. No matter how much you work out, if you’re taking in more calories than you’re burning, you’re not going to lose weight. Changing your diet and eating fewer calories is essential for weight-loss.
