Whether you prefer to lie on the beach, or work out at the gym, there are plenty of opportunities for both, and more, in Livorno.
During the summer, life for the Livornese centres very much around the sea and beach life. Although there is no beach as such in the city, there are many "Bagni" open daily from June to September. A "Bagno" is a kind of private bathing area providing changing facilities, sunbeds and umbrellas, food and drink, sports facilities and evening entertainment. Some even have swimming pools. They are like a sort of private holiday club to which you can take out a season ticket, or pay a daily entrance fee. A Livornese institution, the bagno is the hub of activity all summer long, especially for families and young people.
If instead you prefer quieter surroundings, there are a number of small pebbly beaches in Antignano, and if you prefer the rocks head further south to the spectacular cliffs along the Romito. There are some great "flat rocks" to sunbathe on, and a much more natural setting. Parking can be a problem though, particularly at weekends.
