In gyms, there’s always some free gyan going around ; fitness enthusiasts sharing advice and strategies that are often passed down from person to person, without any scientific basis. This advice is often called "bro science”. 

Picture this: You walk into a gym in India, and a fellow gym-goer confidently tells you that you should consume raw eggs daily to build muscle mass quickly. This bizarre advice is one out of many examples of ‘bro science’.  So if you are new to working out, let's start by understanding what exactly bro science is, and effective tips to help you spot it..

What Is Bro Science?

Bro science is fitness advice based on personal experiences, or unfounded beliefs, rather than scientific research. It is often shared by well-intentioned people who genuinely believe in the advice they share.  It can range from seemingly harmless misconceptions to potentially harmful practices. "I joined the gym to lose weight, and the gym bros told me to exercise on an empty stomach. When I did, I fainted in the gym," said Manan Sachdeva, a 23-year-old businessman.

How To Spot Bro Science

1) No Scientific Evidence

The cornerstone of bro science is the absence of scientific research. Look for reputable scientific studies, peer-reviewed articles, and evidence-based information to back up any advice you receive. If the advice lacks credible sources or relies solely on personal anecdotes, it's likely to be bro science.

2) Promotion Of Supplements

Bro science often promotes the idea that supplements are "miracle" products that help with faster transformation. While supplements can complement a well-rounded fitness routine, they are not a substitute for proper nutrition, training, and overall lifestyle choices. When asked about what's the right time to include supplements, Mohit Gautam, a K11 certified personal trainer and nutritionist, advised that supplements should only be used when you have spent a year training naturally. He further said that you should undergo a blood test before using any supplements, and get your trainer and a doctor’s advice. 

3) Individual Centric

Bro science tends to offer blanket statements or one-size-fits-all advice that does not consider individual differences in body types, goals, or fitness levels. Look for advice that emphasises personalised approaches and takes into account your specific needs and circumstances.

4) Quick Fixes

Bro science often promises quick and dramatic results without putting in the necessary time and effort. Be cautious of claims that guarantee massive muscle gains, rapid fat loss, or overnight transformations.

5) Lack Of Credible Credentials

Pay attention to the qualifications and expertise of the person providing the advice. Certified fitness professionals and registered dietitians can give evidence-based recommendations. While personal experiences can be insightful, it's crucial to consult trusted professionals.


By separating fact from fiction, you can navigate through the sea of information and create a fitness regimen based on sound scientific principles. Remember, your fitness journey should be guided by evidence-based expert advice.
