Whether it's due to a big project at work or problems at home, stress can cause you to lose sleep and make you unhappy. If you have been experiencing anxiety lately, try incorporating physical activity into your daily routine to help relieve some of the stress. According to the Anxiety and Depression Association of America, exercise releases endorphins, helping you feel happier and less stressed. Here are four exercises to try for stress relief:

1. Running

Running is one of the most basic workouts there is and only requires a good pair of gym shoes. As P&G Everyday points out, this activity helps you think and rids your mind of stress. When you finish a jog, you will have a much clearer mind. To make running an even greater stress reliever, listen to music along the way or invite a friend to go with you.

2. Martial arts

Whether it's karate or Taekwondo, martial arts is a great anxiety reliever. According to Arrowhead Martial Arts Studios, this activity requires you to concentrate on your breath, which helps recharge and relax your muscles. If you're more relaxed, you can improve your focus. If you have never practiced this sport before, work with a skilled instructor at a martial arts school in your area.

3. Yoga

Yoga has been around for thousands of years and continues to be one of the best stress relieving exercises. The Mayo Clinic claims that yoga helps both your mind and body achieve tranquility, making it easier to relax and manage stress. Since some poses can be a little tricky, it's a good idea to take yoga classes with an experienced instructor. A good teacher will show you how to do each pose correctly so that you avoid injuring yourself.

4. Team sports

The next time you feel overwhelmed with stress, gather several of your friends or family members and play a team sport, such as basketball, soccer or tennis. You won't just have a blast with the people you care about - you'll also work up a sweat and release endorphins. By the end of the game, you will forget all about what's troubling you.

Incorporating one or more of these exercises in your routine can help you clear your mind and become a more relaxed individual.
