Please choose the correct ending to complete the given sentence: Health: [header] How to lose weight without weighing yourself [title] Set aside 20 to 30 minutes every day to exercise. [step] Your body needs exercise to stay healthy, but that doesn't mean you have to spend hours in the gym. Just 20 minutes of moderate exercise each day can keep you healthy and strong.

Ending1: [substeps] Try walking around the block at least once a day. This can make up for that time you spent holding yourself up through the bench press. Ending2: [substeps] You don't even have to dedicate a single block of your day to exercise. Taking a 10-minute brisk walk in the morning and another in the evening would suffice. Ending3: [substeps] Whether it's walking or jogging, aim to do at least 150 minutes of moderate exercise three days per week. If you have time, or have even a split bedroom, alternate foot exercise with walking, or lifting weights at home. Ending4: [substeps] Plan for an hour a day to walk, spend one hour doing some weight lifting, or just take a walk. Don't limit yourself to just an hour of exercise, rather like a 15 minute walk two times a week.
