So, you’re on the hunt for a digital gym buddy to help you build your dream physique and track your progress?

Here’s why StrengthLog might just be the bodybuilding app that finally makes you stop using a crumpled notebook and a pen that’s perpetually out of ink.

Everything a Bodybuilder Needs. Nothing You Don’t.

This is not a bodybuilding app bloated with features you’ll never use. StrengthLog focuses on what drives results.

  • Effortless Progressive Overload: The app automatically shows your previous performance for any exercise. Your only job is to beat it – the secret to nonstop gains.
  • Proven Bodybuilding Programs: Jump straight into world-class training plans like German Volume Training, PHUL, or our own popular bodybuilding splits. Designed for one thing: hypertrophy.
  • Track What Matters: Instantly see your training volume, set personal records (PRs), and watch your strength graphs climb. Data-driven gains are the best kind of gains.
  • The Ultimate Exercise Library: From compound lifts like squats to the perfect isolation exercise to carve out that bicep peak, we’ve got you covered with clear instructions and videos.
  • Plan, Customize & Adapt: Build your perfect 5-day split, tweak our programs, or add your favorite finisher. Everything you need to train hard and grow is free. Your training, your rules, no restrictions.

StrengthLog is more than a glorified notepad. It’s a bodybuilding app built by lifters, for lifters. Here’s the lowdown on what makes it the best choice for anyone serious about bodybuilding:

A Program for Every Pro (and Newbie)

Whether you’re a seasoned pro who scoffs at anything less than a six-day split or a beginner looking to get started with bodybuilding, StrengthLog has you covered.

You’ll find a smorgasbord of bodybuilding programs, from classic bro splits to more advanced routines. And the best part? A ton of them are free. We’re talking about:

  • Bodybuilding for Beginners: To get you started on the right foot.
  • Upper/Lower Splits: A fan-favorite muscle builder for intermediates to advanced.
  • Push/Pull/Legs (PPL): The holy trinity of bodybuilding workout splits.
  • Bro Splits: Split your body like the pros.
  • Specialized Programs: Want to focus on your “Thicc” lower body or train like the Austrian Oak with Arnold’s own split? You’ve got programs for that, too.

You can also create your own workouts and programs from scratch, so if you’ve got a secret sauce for building biceps, you can plug it right in.

Know Your Muscles, Love Your Muscles

Ever finish a workout and wonder which muscles you actually worked? StrengthLog’s “Muscles Worked” anatomy map gives you a visual breakdown of the muscle groups you’ve worked to make sure you’re hitting everything you need for a balanced physique. No more accidentally skipping leg day!

  • If you’re a premium user, you can create weekly set goals you train to make sure you’re hitting your hypertrophy targets.
  • Set them for all muscle groups or for specific muscles if you want to focus more on weak points.

Track Everything

For bodybuilders, progressive overload is the name of the game. That means constantly challenging your muscles to do more.

StrengthLog makes progressive overload a breeze by tracking:

  • Sets, Reps, and Weight: The bread and butter of any workout log.
  • Personal Records (PRs): StrengthLog tracks your PRs for every exercise and rep count – huge for bodybuilding, where rep ranges are key.
  • Volume: See how much total weight you’ve lifted for a specific muscle group or exercise over time and set goals for your training volume.
  • Advanced Metrics: For the data nerds, StrengthLog tracks everything you need from a bodybuilding app: basic stats and graphs in the free version, plus advanced features like RPE/RiR logging and full training reports in Premium. Invaluable for autoregulating your training.

An Exercise Library That’s Actually Useful

Forget trying to decipher a poorly written exercise description. StrengthLog boasts a massive library with hundreds of exercises, from compound lifts like squats and deadlifts to isolation exercises, mobility drills, and even cardio options.

  • Confidently try new movements without worrying about your form.
  • Video demonstrations and written instructions.
  • Anatomy maps highlighting the primary and secondary muscles you’re targeting with each exercise.

Miss your favorite exercise? Add your own, and track the details that matter to you. There are no restrictions on how many exercises you can create and add, even in the free version.

Clean, Simple, and Ad-Free

Few things kill your pre-lift hype like a pop-up ad.

StrengthLog’s free version is not only free to download and use, but also ad-free.

The interface is clean and intuitive, so you can spend less time fumbling with your phone and more time actually lifting. No ads, no clutter.

“Just an absolute game changer for anyone trying to take their gains more seriously. Whether you’re a bodybuilder, powerlifter or anything in between this is awesome. Even the free version gets you pretty much everything you need.”

FAQ

Here are some of the things you might be wondering. If you have more questions, just download the app and play around. It’s free to get started!

Is the StrengthLog bodybuilding app actually free? What’s the catch?

No catch, no funny business. All the necessary basic features of StrengthLog are free, and you can log unlimited workouts, access a ton of great programs, and track your progress forever.

We do have a Premium subscription for lifters who want to unlock more advanced programs, deeper analytics, and other cool features. But the free version is more than enough to get you seriously strong and muscular.

I’m new to bodybuilding. Is this for me?

Absolutely. Starting with StrengthLog means you’ll build good habits from day one, tracking your progress and focusing on the most important principle of muscle growth: progressive overload.

Our free beginner bodybuilding programs and massive exercise library with video demos will guide you every step of the way.

I’m an advanced lifter. Can StrengthLog keep up with me?

Yes, StrengthLog is built for you, too. We know you care about the details. You can track advanced metrics, build detailed custom programs, and analyze your training volume down to the pound.

This is the powerful logbook you wish you had when you first started lifting.

Can I build my own bodybuilding splits?

You bet. You can build any workout or program you can dream up. Whether it’s a PPL, an upper/lower, a classic bro split, or your own specialized program for bringing up lagging body parts, our workout builder is simple, flexible, and available both in-app and on the web. You’re in complete control.

Does the app track macros or calories?

No. And that’s by design. There are great apps for nutrition tracking, but we believe in doing one thing and doing it perfectly: helping you crush your training. We handle what happens in the gym; you handle what happens in the kitchen.

How is a bodybuilding app better than my trusty spreadsheet or notes app?

Who doesn’t love a good spreadsheet? But let’s be honest, they’re kinda clunky in the gym. StrengthLog is way easier to use between sets of heavy squats.

With built-in rest timers, automatic PR tracking, volume calculations on the fly, and your entire lifting history in your pocket, it’s designed for the gym floor, not a desk.

Why should I trust your word for how good this bodybuilding app is?

You shouldn’t. You shouldn’t trust anyone trying to sell you something, free or not.

Download StrengthLog and see for yourself. There are no hidden catches or ads, and we will never nag you to pay for anything.

And if you want to see if Premium is for you, you can activate a 14-day trial in the app.
