Barry's official description of the workout alternates treadmill intervals with floor strength work, and its Double Floor classes are strength-focused rather than run-focused. Those are two different nutritional emphases in the same studio: run-heavy classes benefit from carbohydrate availability and a settled stomach, while Double Floor days lean on the same protein-and-energy principles as any resistance session. The practical challenge is the schedule — classes are short, popular and often at awkward times for eating.

The official format alternates treadmill blocks with floor strength work, so within one hour you get repeated hard running efforts plus resistance work under fatigue. Double Floor classes drop the treadmill and concentrate on strength.
The running component is what makes meal timing matter more here than in a purely floor-based class: intervals on a treadmill soon after a large meal are unpleasant in a way that dumbbell work is not.
Barry's own workout page is the source for what the class contains. It is official marketing material — useful for format, not for physiology.
The independent evidence that applies is general: protein around 1.4–2.0 g/kg/day for exercising people, resistance-training protein benefits plateauing near 1.6 g/kg/day, and carbohydrate availability supporting repeated high-intensity efforts (PMID 42070893).
How strong is this evidence? No published research evaluates this specific class format's nutrition needs. Everything practical below is general sports-nutrition reasoning applied to a described format.
