Before heading to a court, make sure that you’ve read our rules and regulations. Follow our permit rules, wear smooth-sole tennis shoes, and use a maximum of six tennis balls on each court. Most courts are open from 8:00 a.m. to dusk, except at Central Park where courts open at 7:00 a.m. and Randall's Island where courts open at 7:00 a.m. and close at 7:00 p.m.

I reckon the best thing would be for courses like Tennis Xpress to introduce a ‘recreational’ level for those who want to play on Sundays and may have hit some balls with mates before but who need help correcting technique or gaining more confidence in their game – leaving the very, very rusty or beginners to go slowly without fear of ridicule or frustration.

The components of a tennis racket include a handle, known as the grip, connected to a neck which joins a roughly elliptical frame that holds a matrix of tightly pulled strings. For the first 100 years of the modern game, rackets were made of wood and of standard size, and strings were of animal gut. Laminated wood construction yielded more strength in rackets used through most of the 20th century until first metal and then composites of carbon graphite, ceramics, and lighter metals such as titanium were introduced. These stronger materials enabled the production of oversized rackets that yielded yet more power. Meanwhile, technology led to the use of synthetic strings that match the feel of gut yet with added durability.

Standard squash rackets are governed by the rules of the game. Traditionally they were made of laminated timber (typically Ash), with a small strung area using natural gut strings.[8] After a rule change in the mid-1980s, they are now almost always made of composite materials such as carbon fiber or metals (graphite, Kevlar, titanium, and/or boron) with synthetic strings.[8] Modern rackets are 70 cm long, with a maximum strung area of 500 square centimetres (approximately 75 square inches) and a mass between 90 and 200 grams (4–7 ounces).
The concrete slab should be placed at a thickness of at least 4 inches, or 5 inches if subject to repeated freeze/thaw cycles. Munson's post-tensioned slabs are a minimum of 5 inches thick, with the post-tensioning cables spaced 3 feet apart. Before installing the slab, Munson lays down two layers of 10-mil polyethylene sheeting to reduce drag as the slab shrinks upon curing and to serve as a moisture-vapor barrier.
Tennis is played by millions of recreational players and is also a popular worldwide spectator sport. The four Grand Slam tournaments (also referred to as the Majors) are especially popular: the Australian Open played on hard courts, the French Open played on red clay courts, Wimbledon played on grass courts, and the US Open also played on hard courts.
