1. Develop a habit of exercising

Make everything a habit, whether it's exercise or a proper diet—it really requires sufficient desire and motivation. One way to help cultivate an exercise habit is to visualize the benefits of exercise, imagine your body burning fat rapidly, and your own slim figure; this will help motivate you.

2. Start exercising slowly.

Just as you can't get fat overnight, you can't lose weight with just one workout. Starting by climbing 23 flights of stairs or running around a track for an hour will definitely discourage you, and feelings of frustration, aches, and pains will easily drag you back to your old ways. When starting a sport, begin with a small amount of exercise, gradually adapt, and increase the intensity.

3. Find a workout partner

Whether exercising alone or in a team, it's a joyful experience to work out with a like-minded partner. They are also a great motivator, as they create a sense of responsibility and won't discuss their motivation to give up in front of their friends. Try to choose someone with a similar body type as your workout partner.

4. Do the sports you enjoy.

Most people will develop their own exercise habits during college, and have at least one sport they particularly enjoy. If you want to try a new sport, stick with it for at least three weeks. If you still don't like it after three weeks, then give it up. Then look for other forms of exercise until you find one you enjoy.

5. Muscles make people slimmer

One thing must be made clear: appropriately increasing muscle mass will never change your original beautiful physique. This is not about training you to be a top athlete. Appropriate exercise will only make your physique more beautiful, boost your metabolism, and make you more energetic and healthy.
