Divock Origi and Dejan Lovren undertook lactate testing as they began pre-season training at Melwood on Tuesday morning, with the rest of their teammates also taking part in a series of workouts.
Liverpool will contest their first pre-season friendly of the summer against Tranmere Rovers at Prenton Park on Thursday night - a game you can watch live on LFCTV and LFCTV GO - and preparations were continuing towards the fixture at the club's West Derby complex.
You can see the best of the session in our video above now.
