I’m here to have a go at ‘Lift Club’, a 45-minute class on offer in select gyms that runs in six-week cycles and is open to all levels — even, I am assured, complete beginners. The tagline runs: ‘Squat, press, pull and deadlift your way to a noticeably stronger body focusing mainly on barbell compound movements and short, sharp conditioning work.’ I had pretty much no idea what that meant in practice.
