The Claim

Low-dose acetylsalicylic acid (75 mg/day) does not impair muscle hypertrophy or strength gains during 8 weeks of resistance training in young adults, with a reported 7.5% increase in quadriceps muscle volume, suggesting it may be a safer anti-inflammatory option for individuals engaged in strength training.

Support is ahead, but a single strong opposing study can change this.

In plain English

Taking a low-dose aspirin every day doesn’t seem to slow down muscle growth or strength gains when young adults do weight training for 8 weeks — and they still gained about 7.5% more quad muscle size, so it might be a safer anti-inflammatory choice for lifters.

Low-dose acetylsalicylic acid (75 mg/day) does not appear to impair muscle hypertrophy or strength gains during 8 weeks of resistance training in young adults, with a 7.5% increase in quadriceps muscle volume observed, suggesting it may be a safer anti-inflammatory option for those engaged in strength training.

What the research says

1 study
  1. Study: High doses of anti‐inflammatory drugs compromise muscle strength and hypertrophic adaptations to resistance training in young adults

    The study found that taking a low dose of aspirin (75 mg) every day didn’t stop muscles from getting stronger or bigger during training, which supports the idea that it’s a safe option for people doing strength workouts.
