Another significant social advantage of group exercise is the opportunity to develop, refine, and use your social skills. Depending on the sort of exercise, abilities such as teamwork, leadership, and communication may be required. Group exercises are also great ways to meet new people with similar interests and hobbies. Classes can be more intimate than groups, but not all people enjoy being alone when they exercise. If you prefer to have company while working out, then look for classes that allow both group exercise and individual instruction. This way you can work out with others while getting advice from instructors about how to improve your form or technique. Some classes will include music during certain parts of the workout. You can join in if you want, but it's not essential for the enjoyment of the class. For example, classes called "bootcamp" or "punishment laps" might use heavy weights or athletic equipment, including treadmills, bikes, and rowing machines. These classes are great ways to get in a full body workout in just an hour. Other classes are designed to target specific muscles or muscle groups. For example, there are yoga classes, pilates classes, and zumba classes. These classes usually focus on relaxation techniques, strengthening exercises, and dance moves, respectively.
