Andy Robertson kicked off his pre-season programme in Austria on Friday morning by undertaking lactate testing.
Following a summer break after captaining Scotland at Euro 2020, the left-back arrived at Liverpool’s training camp earlier this week.
And Robertson got down to work today in Salzburg, with the exercise that measures a player’s endurance levels with runs of increasing speeds.
