Summarize this article:

There’s no point forcing yourself to do a kind of exercise that you hate. That won’t last very long! Instead, find an activity you enjoy. You may have to try out a lot: yoga, dance, soccer, basketball, swimming, jogging… The options are limitless! You may find you enjoy energetic team sports, like baseball, or that you prefer the solitude of a long walk in nature.   Once you’ve found a physical activity that you enjoy, aim to do it at least 3 times a week. Try to do some other kind of physical activity 2 other days a week. For example, if you love playing basketball, try playing basketball 3 times a week, and lifting weights twice a week. Switch activities if you get bored. If you get injured, stop doing that activity and go see the doctor. The best way to motivate yourself to keep exercising is to have other people counting on you to show up. Then you can nag them to show up, they can nag you… A perfect arrangement! If you don’t know anybody who likes to exercise, go to your local YMCA or join a sport or a club at your high school. Or, you can encourage your friends to start working out with you. Plan healthy rewards afterward to make the event more fun and enticing. Like, we’ll all go to yoga together, and then get coffee. Or, let’s go to the gym, and then go eat dinner. This doesn’t have to be intense! Just make sure you’re moving, whether that’s walking, biking, lifting weights, chasing your little cousin around the park, or playing basketball. You don’t have to have the hour of movement be all in one go. For example, you could walk your dog for 30 minutes before school, and then play soccer with some friends for 30 minutes after school. The weights section of the gym might by intimidatingly crowded with boys, but it’s time to change that! Girls need to be strong to be healthy, and lifting weights is a great way to lose fat and gain muscle. You should exercise your arms, legs, and abs. You can start with body-weight exercises, like push-ups and crunches, and work up to using the weights. If you’re not sure how to use the weights, a lot of gyms have introductory lessons, or ask someone you know to give you a lesson. Working out your whole body is what’ll make you lose weight, but you can get defined abs by adding in some ab exercises. Try doing planks, where you hold yourself in a push up position with your arms straight or resting on their elbows. Keep your body in a flat line. Hold the position for 30 seconds, and work up from there.  Also do leg lifts, where you lie flat on your back and lift your legs up off the ground and back down. Remember that doing abs alone won’t burn belly fat, but it will build muscle. Take rest days in between your ab workouts.
Find a physical activity that you enjoy. Find positive friends to exercise with. Aim for 1 hour of physical movement every day. Do strength-training and weight-lifting about twice a week. Tone your abs with ab exercises.
