not enough fatty ;)
You can run or walk everfay after school for a 30 minutes at the least.
Unless you have your diet under control - nothing. 30 minutes of low intensity workout is too little to change things if you're overeating.
Walk Walk
You could walk five miles a day and gain weight. Losing weight depends on eating less calories than you expend. Walk or run if you can run without injury and eat less, means you will loose weight.
We can't estimate without knowing how many calories you're taking in, and the intensity of your exercise.
Try this because I lost 17lbs in 10 days : bi t.ly/3eRPjvN (remove the space)
you can make them walk with you
Not necessarily. To lose weight you must use, or burn, more calories than you take in.
How much weight you might lose depends on your current weight, your degree of fitness, your body composition, and where you are walking (flat ground or incline) as well as how far you are walking and how fast you are walking. Walking to lose weight is mild cardio exercise and very effective for weight loss when done correctly. Unlike running, it is easier on your body and it is sustainable long term. To learn how to do it correctly, see the page link, further down this page listed under Related Question.
Walking a half mile is a great "little boost," but you're not going to lose any weight. Your weight, height, gender, exercise level and caloric intake are huge factors. If you walk a half mile to Dairy Queen...I mean, come on...no weight loss. If you factor in a half a mile a day with proper diet and (additional exercise) you will lose weight....slowly. Good luck.
It doesn't matter much on how long you walk but more with how far you walk. For example if you were to walk a total of 10 feet in 45 minutes it would not help you much. Another point to look at is that you may reach a point that muscle gain may partially(or fully, i dont know)make up for your weight loss. While you may be dropping waist sizes your weight could go nowhere.
2 hours per day?
