If you keep meaning to start a new sport and keep finding excuses to put off the first session, Etimesgut Belediyesi Yarı Olimpik Kapalı Yüzme Havuzu ve Spor Kompleksi over in Tunalı could be the starting point. Gyms and facilities get packed at prime time, empty outside it — know your hours and you'll catch the quiet sessions. The first few weeks are the hard part; after that the habit runs itself and motivation stops mattering.
