Doing supervised, short bursts of intense exercise like sprinting or cycling hard for six months can shrink the fatty buildups in your arteries—just as well as, or even better than, taking cholesterol-lowering statin pills.

Assessment Explanation
While some studies suggest HIIT may reduce plaque burden, no randomized controlled trial has directly compared supervised HIIT to statin therapy over six months and demonstrated non-inferiority or superiority in plaque regression as a primary outcome. Plaque regression is a complex, slow process typically measured via intravascular ultrasound or CT angiography, and statins have robust, reproducible evidence for plaque stabilization and modest regression. The claim implies equivalence or superiority without direct comparative evidence, making it overstated. The verb 'induces' is too definitive; 'may contribute to' or 'is associated with' would be more accurate.
More Accurate Statement
“Supervised high-intensity interval training (HIIT) over six months may contribute to a reduction in atherosclerotic plaque volume, with potential effects that warrant further comparison to statin therapy.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
High intensity interval training induces beneficial effects on coronary atheromatous plaques - a randomized trial.
This study found that people who did supervised high-intensity workouts for six months had less plaque buildup in their heart arteries, which means HIIT can help reverse heart disease damage — just like the claim says.
