Is the afterburn effect really a thing or just marketing hype?
I've been diving into the research on the afterburn effect (EPOC), and I'm seeing mixed messages. A meta-analysis by Børsheim & Bahr (2003) suggests that while EPOC exists, the effect sizes are often small and vary depending on intensity and duration of exercise. In Schoenfeld's (2016) work, he points out that while high-intensity training can increase EPOC, it's still relatively minor compared to total caloric expenditure from the workout itself. I'm curious, for those who've tracked their data, has the afterburn actually impacted your results, or is it just another fitness myth?
