Gym for Beginners: The Ultimate Guide for What Truly Matters

Training. Nutrition. There are so many things you should optimize when you're a beginner at the gym. Good news: not all matter for progress.

Gym for Beginners: The Ultimate Guide for What Truly Matters

It’s January, which means you’re making good on that go-to-the-gym New Year’s resolution of yours … right? *lifts eyebrow*

Whether you’re 10 sessions deep (🎉) or planning to hit the gym soon-ish, we figured you'd appreciate a handy compilation of everything that’ll truly move the weight loss and/or gains needle — so you aren’t left spinning your wheels.

#1: Adequate training volume

For those of you who’d like to lose weight, you may be wondering:

"Why should I care about training volume? Isn't that more applicable for those who want to maximize muscle growth?”

See, here’s the thing. When you’re in a calorie deficit, your body doesn’t care how it sheds the weight, just that it does, meaning you'll lose fat and muscle mass. Now, the former: that's your goal. I.e., it's celebration-worthy. But the latter?

Research shows that the more muscle mass you lose during a diet, the:

  • More hunger you tend to experience later, which
  • Jacks up the likelihood of you regaining the weight you’ve lost post-diet 🫣

And that’s why you should care about adequate training volume even though you’re gunning for smaller numbers on the scale; because it tells your body to hang on to its muscle mass (how else would it handle an 80-kg barbell squat?) and prioritize fat loss instead.

OK. So, what counts as “adequate” training volume?

It depends on your lifting experience (and, as explained earlier, not on your body composition goals).

To get exact numbers on the sets + reps you should do as a beginner at the gym:

The higher your training volume, the more gains you’ll get ... right? Wrong. Find out exactly how many sets and reps you should do right here.

#2: Proper nutrition

As surprising as this may sound, the primary difference between a diet geared for:

  • Weight loss vs
  • Muscle growth

… is energy balance. Or how many calories you eat above/below your maintenance calories.

With a weight loss goal, to escape relatively unscathed from the adverse metabolic adaptations to a calorie deficit (we’re talking muscle mass loss, subconscious reductions in daily step count, increased hunger, and more), research suggests you’d do best with a moderate, 15% to 25% deficit.

In other words, if your maintenance calories are 2,100, your target intake would range from 1,575 (0.752,100) to 1,785(0.852,100) calories.

On the other hand, if you’d like to get a bigger back, shoulders, glutes — well, just about everything, then you’ll need a slight calorie surplus. Slight: i.e., nothing too crazy, typically around 10% to 15% above your maintenance calories — otherwise, you risk putting on too much fat.

So, once again, going back to our hypothetical maintenance calories of 2,100, your target intake would range from 2,310 to 2,415 calories.

Besides the number of calories, the basics of "proper nutrition" for a weight-loss or gains-geared diet are, TBH, unexciting. It involves:

#3: Have realistic expectations

As a beginner to the gym, how long do you think it’ll take for you to achieve your body composition goals?

Take that figure and double it. Maybe even triple it for good measure.

To quote Matthew Kelly in “The Long View”:

“Most people overestimate what they can do in a day, and underestimate what they can do in a month. We overestimate what we can do in a year, and underestimate what we can accomplish in a decade.”

Don't expect to drop 3 sizes or look like your fav ripped fitness influencer in 3 months — then get disappointed and throw in the towel when the time's up, and you're still 10,000 miles away from your goals.

If you’d like to calculate the exact number of weeks you need to bag your dream physique (for realistic expectations):

#4: Don’t strive for perfection; just start

You know what you should do — in terms of training volume and nutrition — to realize your fitness goal.

Now, please know you don't have to nail everything down right from the start.

That's waaaaay too much pressure.

Instead, start small and slow. Maybe start going to the gym 1x a week instead of not going. Meal prep 4 meals weekly instead of eating out daily.

When it comes to progress, remember this: consistency > perfection.

Think that sounds like a lie we tell ourselves to feel good?

This 2017 study published in the Journal of Diabetes Research is here to change your mind. So, the researchers got the participants to track their food intake over 12 months. At the end of the study, they divided the participants into 3 groups:

Rare trackers (< 33% of total days tracked)
Inconsistent trackers (100% on some days, but less than 30% on others, which made for 33% to 66% of total days tracked)
Consistent trackers (> 66% total days tracked)

… and found that only consistent trackers experienced significant weight loss of 4.5 kg (9.9 lbs.).

Evidence that consistency is truly what’ll move the progress needle.

On that note, you can’t be consistent without first starting. And a crucial piece of advice here is: don’t overthink your training or nutrition plan.

Most beginners going to the gym needlessly fiddle with the specifics (e.g., Should I do the leg press or barbell squat? Should I drink a protein shake before bed?) so much that they’re stuck in a state of inaction. Don’t miss the proverbial forest over the trees.
