The Brazil international has regularly posted clips of his training sessions over the past month or so despite being on a summer break following a gruelling season.
Lucas started his bid to be fully fit for pre-season with runs around his farm before he ventured into the gym with his own coach to carry out a series of exercises.
And on the eve of his return to Liverpool, Lucas uploaded a video of a speed session which involved the use of a parachute to provide resistance.
Lucas wrote on his Instagram page: “Last session in Brazil. Tomorrow get back to Liverpool .”
The Liverpool midfielder is facing a battle to secure a place in Brendan Rodgers’s starting line-up next season following the signing of James Milner.
He experienced an injury-hit season due to a groin problem before the South American made a successful return in the second half of the season.
Lucas made 20 Premier League appearances for the 18-time English champions last season as he helped Liverpool go on a lengthy unbeaten run before injury struck.
