This week Liam has to create a fitness vlog. For inspiration, he meets kale-obsessed vlogger, Polly Sprong, aka 'The Hectic Yoga'. And he goes for a gym session with self-titled 'alpha vlogger', Johnny Jackson.
For his third challenge Liam has to create a viral music video. Charlie South introduces him to international grime star, 'Bombzy'. And Liam's unusual music tastes cause some strange behaviour from Millipede.
