You're looking for a solid workout plan. You type a search into Google and two names dominate the results: Bodybuilding.com and Reddit. One is a polished, commercial giant with decades of content. The other is a sprawling, chaotic community of real people. Both promise results, but their advice often conflicts. So, which one should you trust?
This is a critical question, because the program you choose determines the results you get. The wrong advice can lead to months of wasted effort, frustration, and even injury. The right advice can be the key to unlocking consistent, long-term progress.
In this article, we’ll provide an objective, head-to-head comparison of Bodybuilding.com and Reddit. We'll analyze the pros, cons, and reliability of each platform. But we'll also reveal a more important truth: the best source of advice isn't a website. It's a principle. Once you understand this single, powerful concept, you'll be able to filter the good from the bad on *any* platform and build a physique that lasts.
Before we get to the master principle, let's directly compare the two platforms. They serve different needs and come with unique strengths and weaknesses.
Bodybuilding.com is one of the oldest and largest fitness sites on the internet. It's a massive repository of articles, exercise guides, and structured workout programs, often created by well-known fitness personalities.
Pros:
Cons:
Reliability Verdict: Moderately reliable, with a major caveat. The classic, time-tested programs (like Layne Norton's PHAT) are generally built on solid principles. However, you must be highly skeptical of any content that pushes a specific supplement as the 'key' to success. Use it for its structured plans and exercise library, but view its commercial content with caution.
Reddit is a collection of communities (subreddits) where users share and discuss information. For fitness, the most valuable subreddits are r/fitness, r/weightroom, and r/bodybuilding.
Pros:
Cons:
Reliability Verdict: Highly reliable, if you stick to the right places. The curated wikis and recommended programs are excellent and evidence-based. Individual user comments and posts should be treated with extreme skepticism until you can verify the information from a trusted source. The wiki is your safe harbor.
So, which is better? The answer is neither. The most effective programs from Bodybuilding.com and the most recommended routines on Reddit are all built on the same foundation: progressive overload. This is the non-negotiable, universal law of muscle growth.
Progressive overload means that in order to get bigger and stronger, you must continually make your muscles work harder than they are used to. Any advice that helps you systematically do more work over time is good advice. Any advice that distracts from this is noise.
This is measured by your total weekly volume. This single metric is the key to unlocking progress.
Most people stall because their workouts lack a mathematical progression. Muscles are incredibly efficient at adapting. They adapt to a specific workload within a few weeks. If that workload doesn't increase, the muscle has no biological reason to grow larger or stronger. This is the root cause of almost every plateau.
Many free programs, especially those focused on 'muscle confusion' or endless variety, fall into this trap. They feel difficult and entertaining, but they often fail to increase the one metric that matters: total weekly volume. This is the total amount of weight you lift for a specific muscle group in a week. The formula is simple:
Sets × Reps × Weight = Volume
For example, if you bench press 3 sets of 10 reps at 150 lbs, your volume for that session is 3 x 10 x 150 = 4,500 lbs. If you do that twice a week, your total weekly volume for that movement is 9,000 lbs.
Most advice on Reddit threads or Bodybuilding.com articles never mentions tracking this number. Instead, they suggest changing exercises, routines, or rep schemes. This feels productive but often fails to increase total volume. The secret isn't a new exercise. It's doing more total work over time. The platform you choose is irrelevant. The only thing that matters is whether a program systematically increases your total weekly volume.
Use this system to evaluate any workout plan you find, whether it's from a glossy magazine, a Reddit wiki, or a famous YouTuber. It forces you to look past the marketing and analyze the mathematical structure that drives results.
Before you can progress, you need to know your starting point. Pick one main compound exercise for a major muscle group (e.g., bench press for chest, squat for legs). Look at your training log for the past week and calculate the total volume for that single exercise.
*Example:* Last week, you did the following for squats:
You must know this number. It is your primary benchmark for progress.
Now, examine the program you're considering. Does it explicitly state how you are supposed to get stronger? A good program will have a clear, built-in progression model. Look for instructions like:
A bad program is just a list of exercises and set/rep schemes with no instructions for how to advance. If the plan for progression isn't obvious and written down, the program is incomplete and likely ineffective long-term.
Your goal is to increase your total weekly volume by a small, sustainable amount each week. A 2-5% increase is the sweet spot for most intermediate lifters. It's enough to stimulate growth without exceeding your body's ability to recover.
Using our squat example with a baseline of 9,075 lbs, a 3% increase is about 272 lbs. How can you achieve that?
This simple change increases your total weekly volume well within the target range. You can track this in a notebook or a spreadsheet. As a convenient shortcut, an app like Mofilo can automatically calculate your volume (sets × reps × weight) for every workout, making it easy to see your progress and ensure you're consistently applying overload.
Progress will feel slow, but it will be undeniable. You won't be able to add 5% to your volume every single week forever. Life happens. Some weeks you'll feel strong; others you'll be tired. The goal is a clear upward trend on a monthly and quarterly basis.
After 6-12 weeks of consistent increases, you will likely need a deload week. This is a planned reduction in training stress to allow your body to fully recover and dissipate accumulated fatigue. A typical deload involves reducing your total volume by 40-50% for one week. This is a critical part of smart, long-term training, not a sign of failure. True strength is built over years, not weeks. This method ensures you are always taking one small, measurable step forward.
Reddit's curated wikis (like in r/fitness) are excellent and evidence-based. However, you must vet any advice from individual user posts using the 3-step volume system. Do not follow a program just because it's popular in a single thread.
Some older programs on the site are built on solid principles of progressive overload. Many newer ones are designed as marketing funnels for supplements. Use the volume-vetting system to determine if a program has a clear, logical progression model.
Increasing weight is only one way to increase volume. You can also add one rep to each set (e.g., go from 3x8 to 3x9) or add one extra set (go from 3x8 to 4x8). The goal is to increase the total product of (Sets × Reps × Weight), not just the weight on the bar.
You should only change your program when you have genuinely stalled for 2-3 consecutive weeks despite consistent effort, good nutrition, and adequate sleep. 'Program hopping' is one of the biggest mistakes beginners make. Stick with a program as long as your weekly volume is trending upwards.
