Strategic Fuel Station Placement Boosts Carb Intake and Recovery
Something seemingly so simple as putting a fuelling station in the right place can be the difference between players achieving total daily carb intakes or recovering optimally the day before a match. Simple strategy. Big pay-off. tomcoughlin.co.uk #nutritionist #nutrition #performancenutritionist #sportsnutrition
