Aspirin, Ibuprofen May Blunt Muscle Gains From HIIT
news · 2026-07-29 · Mindbodygreen
Common over-the-counter anti-inflammatory meds like aspirin and ibuprofen might block some of the muscle-building and cardio benefits of high-intensity interval training (HIIT), according to a new study from Swedish researchers published in Acta Physiologica. The study involved a small sample of 31 young adults, tracking their muscle growth and anti-inflammatory markers after HIIT sessions.
Sabin's take. Thought your post-workout ibuprofen was helping? Turns out, it might be sabotaging your gains. This isn't just about pain relief versus hypertrophy; it's about the body's natural inflammatory response after a hard session being a signal for adaptation. Pop an NSAID, and you're potentially muting some of the cellular messages that tell your muscles to grow stronger and your heart to get fitter. The study was small, sure, but it adds to growing evidence that chronic anti-inflammatory use can dull the very adaptations we're chasing with exercise. Maybe that little bit of discomfort is actually part of the process, a chemical cue for your body to level up. Think of it less as pain to be conquered, and more as information to be processed. What's next? Expect more athletes and weekend warriors alike to rethink their immediate grab for the Advil after a tough workout.
