The Liverpool squad kicked off preparations for the 2013-14 campaign with intensive training sessions at Melwood this week – including a succession of hurdle challenges snapped by our photographer.

Regular faces such as Philippe Coutinho and Steven Gerrard have been joined by summer signings Luis Alberto, Iago Aspas, Simon Mignolet and Kolo Toure at the club's training complex.

In addition to ball work, we have images of the players testing their agility and reflexes with a series of jumps; take a look for yourself by browsing through our slideshow below.

Following the launch of the club's new 2013-14 Warrior third kit on Thursday, the squad trained in the black, purple and white strip throughout the day.

The new strip is available to pre-order now at our online store and official LFC club shops, with free name and number printing on offer with each purchase and guaranteed worldwide delivery on launch date, August 1.
