19 Popular Fitness Beliefs Ranked: Overrated or Underrated? A No-Nonsense Breakdown by Experts
In the ever-evolving world of fitness, certain ideas get praised to the heavens—while others are harshly dismissed. But which common training and nutrition concepts actually hold up under scrutiny, and which are simply outdated myths? To cut through the noise, we’re diving into 19 hot-button fitness topics, examining whether they’re overrated or deserve more credit. With expert insights from a seasoned bodybuilder and exercise scientist, this article breaks them down across three major categories: training, nutrition, and general fitness culture.
TRAINING TOPICS
1. Cheat Reps (aka Ego Lifting)
Used sparingly, cheat reps might help squeeze out one or two extra reps. However, overreliance on momentum often compromises form, increases injury risk, and shifts tension away from the targeted muscles. Verdict: Overrated, especially for beginners.
2. Muscle Soreness
DOMS (delayed-onset muscle soreness) can signal that your muscles were challenged—but it’s not a reliable marker of progress. Growth can still happen without soreness. That said, persistent lack of soreness combined with stalled progress could indicate undertraining. Verdict: Slightly overrated but context-dependent.
3. Bro Splits (Training Each Muscle Once Per Week)
While training each muscle group weekly is popular in traditional bodybuilding, it often misses the mark on volume and frequency. Most muscles recover faster and can be trained more often for better growth. Verdict: Mostly overrated, with some value for large muscle groups.
4. Training to Failure
Going all the way to muscular failure isn’t always necessary. Studies show similar growth results whether you stop just short or push to failure, especially if your training is already intense. It’s important to know what failure feels like, but constantly pushing to it can increase fatigue. Verdict: Properly rated, but often misused.
5. Mind-Muscle Connection
Consciously focusing on the muscle you’re training can enhance engagement, especially during isolation movements. However, obsessing over it at the expense of progressive overload and good form can limit gains. Verdict: Moderately overrated—use it as a tool, not a rule.
6. The Muscle Pump
Getting a good pump feels great and often correlates with effective training. While it’s not the only signal for growth, it can help ensure that you’re targeting the right muscle. Verdict: Underrated, especially in hypertrophy-focused programs.
NUTRITION MYTHS & REALITY
7. Dirty Bulking
Packing on mass through unrestricted eating may increase strength short-term, but most of that gain is fat—not muscle. Excess fat comes with metabolic and aesthetic downsides. Verdict: Overrated—lean bulking is a smarter long-term strategy.
8. Natural Testosterone Boosters
Despite the hype, over-the-counter “test boosters” rarely deliver measurable effects. True hormonal change requires clinical intervention. Verdict: Highly overrated and mostly ineffective.
9. 1 Gram of Protein per Pound of Body Weight
While slightly more than necessary, this simple guideline ensures most people consume enough protein for muscle repair and growth. It’s practical and easy to follow. Verdict: Properly rated—especially useful when cutting.
10. Body Recomposition (Gaining Muscle While Losing Fat)
Despite the skepticism, many people—especially beginners or those returning from a break—can successfully build muscle and burn fat simultaneously. However, this method becomes less effective as training age increases. Verdict: Underrated for novices, but limited over time.
11. Diet Soda
Contrary to popular belief, artificially sweetened beverages are not harmful in moderation. They can be a useful tool for managing cravings and controlling caloric intake. Verdict: Underrated, especially for those trying to lose weight.
12. Diet Breaks
Taking short periods off from a calorie deficit can support adherence, improve training, and help reduce diet fatigue. There’s no rush to reach your goal overnight. Strategic breaks often yield better long-term results. Verdict: Underrated, especially during extended fat loss phases.
13. Clean Eating
The term “clean” is vague and varies by person. Demonizing certain foods can lead to disordered eating patterns. Focusing on nutrient density without total restriction is more sustainable. Verdict: Overrated when taken to extremes, but minimizing ultra-processed food still has merit.
HOT FITNESS TOPICS
14. Natty or Not Speculation
Debating whether influencers are “natural” often leads to baseless accusations and toxic comparisons. Unless someone is openly lying, obsessing over their PED use does little to benefit your training. Verdict: Overrated and often unnecessary.
15. Enhanced vs. Natural Training Styles
While enhanced lifters might recover faster, the core training principles—progressive overload, proper form, and recovery—don’t change. Steroids don’t rewrite the rules of physiology. Verdict: Overrated—the basics still apply to everyone.
16. Cold Showers for Recovery
The hype around cold exposure has outpaced the science. In fact, cold therapy post-training may blunt hypertrophy. While it may offer mental or mood benefits, it’s not a recovery necessity. Verdict: Overrated, especially for muscle growth.
17. NoFap (Semen Retention)
There’s no solid evidence that abstaining from masturbation significantly boosts testosterone or training performance. It’s a personal or cultural decision, not a performance hack. Verdict: Overrated, and largely based on pseudoscience.
18. Locking Out Knees During Lifts
Contrary to popular belief, locking out your knees during exercises like squats or leg presses isn’t inherently dangerous. Your joints are designed to lock out under control. Verdict: Overrated fear—this is more myth than science.
19. Filming in the Gym
Recording your workouts is a powerful tool for self-assessment and education. As long as you’re respectful of others’ space, there’s nothing wrong with capturing your training. Verdict: Underrated, especially for content creators and lifters wanting to improve technique.
Final Thoughts
Fitness myths are everywhere, and it’s easy to fall into the trap of following outdated advice. Whether it’s a trendy diet, a controversial training method, or common gym folklore, questioning what you hear is crucial. By evaluating these topics through the lens of experience and evidence, you can make smarter decisions that lead to better results—and fewer wasted efforts.
