assertion
Analysis v1
When you lift weights, your body uses stored energy (creatine phosphate) and fat for fuel—not just sugar.
Scientific Claim
High-intensity resistance exercise derives a substantial portion of its energy from the creatine phosphate system and aerobic fat oxidation, particularly during rest intervals.
Original Statement
“Much of the energy production during high intensity exercise comes from the creatine phosphate system, not carbohydrates, and there's also a very significant component of aerobic metabolism, meaning fats are still used for energy relying on oxygen, because a lot of that can take place in between sets.”
