Local recreation centers are found in most communities throughout the country. They offer a range of services to their clientele. Local recreation centers in larger cities typically have more abundant facilities and are able to provide a wider array of opportunities for recreation and improving ones health. Most local recreation centers are outfitted with exercise equipment such as treadmills and stationary bicycles. These machines will vary in number and quality, based on the centers budget. Centers commonly also have an indoor track for walking or jogging. Many local recreation centers also have weight machines, and some may make free weights available to their clients, too. Larger local recreation centers have trainers on staff to help clients learn how to use the equipment in a way that is safe and which will guarantee the best workout possible. New clients should seek out these staff members for instructions on any apparatus they are not familiar with, to prevent the risk of injury. Basketball, volleyball, and racquetball courts can be found in many local recreation centers, too. They may be available on a first come, first served basis, or there may be opportunities to reserve these courts ahead of time. At times, an additional fee will be charged to use these courts, though often certain times are designated as open basketball, for example, in which no fee is assessed. These local recreation centers may also host leagues in these various sports. Teams are divided by skill level, with some leagues being more competitive and others more focused on simple recreation. Local recreation centers provide classes for clients in exercise disciplines such as aerobics, yoga, Pilates, and sometimes karate or judo. These classes are usually divided into various skill levels, and also into classes for adults and youth. There is often a fee to join these classes. The courses are taught by trained and experienced instructors who will help attendees get maximum benefit from their workouts. In some instances, these instructors may be available for private lessons at the local recreation center, to provide clients with individual and specialized attention. Prices for such instruction will vary.
