Feeling lost on how to track your gym sessions is completely normal. You see people with detailed notebooks or complex apps and feel like you're miles behind. This guide will show you how to start logging your workouts if you feel clueless, using a simple method that requires nothing more than a pen and paper.
If you're asking 'how do I start logging my workouts if I feel clueless,' it’s because you think the process is far more complicated than it really is. The truth is, you only need to track 3 simple numbers to build muscle and get stronger. The fitness industry profits from complexity, pushing apps with dozens of features and influencers with color-coded spreadsheets. It's overwhelming by design.
You feel clueless because you're experiencing paralysis by analysis. Should you track rest times? Lifting tempo? Rate of Perceived Exertion (RPE)? The angle of the bench? The answer for a beginner is no. None of that matters until you master the fundamentals.
Trying to track everything at once is like trying to learn calculus before you can add. It guarantees failure and makes you feel like the problem is you, not the method. It's not you. The problem is starting with too much information.
The sole purpose of a workout log for the first year is to answer one question: "Am I doing more than I did last time?" That's it. Your log is not a diary. It's not a record of your feelings. It is a simple data tool to ensure you are applying progressive overload, which is the non-negotiable principle of getting stronger.
Forget the fancy apps for now. Grab a cheap spiral notebook and a pen. This simple toolkit is what built most of the strong physiques you see in the gym today. It's simple, it's effective, and it's impossible to get wrong.

Track your lifts in Mofilo. Know you are getting stronger every single week.
To go from clueless to confident, you will track only three things for every single exercise you do. This is the foundation. Everything else is noise until you have this down for at least three months.
Be specific. Do not write "Chest Press." Write "Incline Dumbbell Bench Press" or "Flat Barbell Bench Press." Why? Because 100 pounds on a flat bench is not the same as 100 pounds on an incline bench. Specificity allows for true apples-to-apples comparison week over week.
Your log for the day might start with the date, then the first exercise:
October 26, 2025
Goblet Squat
This is the total resistance you are moving.
After each set, immediately write down the number of successful reps you completed. Don't wait until the end of the exercise or you will forget. If your goal was 10 reps but you only got 9, you write down 9. Honesty is critical.
Here is what a complete entry for one exercise looks like:
Goblet Squat
That’s it. That is the entire system. You repeat this for every exercise in your workout. It takes 15 seconds after each set. You now have perfect data to ensure you get stronger next week.
A workout log sitting in your gym bag is useless. Its power is unlocked when you use it to plan your *next* workout. This is how you apply progressive overload and force your muscles to grow.
Before you even touch a weight, open your notebook to last week's entry for that same workout day. Find the first exercise. Let's use the Goblet Squat example from before:
*Last Week: Goblet Squat - 40 lbs for 12, 10, 9 reps.*
You have two primary ways to beat this log entry:
Your mission for that exercise is now crystal clear. You're not just "working out"; you're on a specific mission to beat a number.
Let's say you chose to increase the weight. You picked up the 45 lb dumbbell. You fought hard and managed 9 reps on the first set, 7 on the second, and 7 on the third. You immediately write that down:
Goblet Squat
Congratulations. You have successfully achieved progressive overload. You lifted more weight for a solid number of reps than last week. You gave your body a new reason to adapt and get stronger. Next week, your goal will be to beat *this* new entry, perhaps by doing 45 lbs for 10, 8, and 8 reps.
This simple cycle of Review -> Target -> Execute -> Record is the engine of all physical progress in the gym.

See every workout you've ever done. Watch your strength numbers climb over time.
Even with a simple system, you'll run into roadblocks. Here’s how to handle them without getting discouraged.
Logging "Leg Day" or "Shoulder Press" is a waste of time. There are a dozen types of shoulder presses, and your strength on each is different. If you did Dumbbell Shoulder Press last week and try to beat your numbers on a Barbell Overhead Press this week, the data is meaningless. Be hyper-specific with exercise names.
Don't trust your memory. It will fail you. You'll think you did 10 reps when you only did 8. This leads to fake progress and frustration when you can't replicate it. Keep your notebook with you and log each set the moment you finish it. It takes 15 seconds.
You will have bad days. Poor sleep, high stress, or a missed meal can easily cause a 10-15% drop in strength. If you benched 135 lbs for 8 reps last week and can only get 6 this week, do not panic. It is not a sign that you're getting weaker.
Just log the numbers honestly and move on. As long as the trend over 3-4 weeks is moving up, you are making progress. One bad data point is just noise, not a trend.
Your logbook will get messy. You'll spill water on it. You'll scribble notes. It doesn't matter. This is a tool, not a piece of art. A messy, used logbook is a sign of hard work. Don't let the desire for a perfect-looking log stop you from using it effectively. Done is better than perfect.
A simple notebook is better for beginners. It forces you to focus on the essential metrics without the distraction of a phone or the complexity of a feature-heavy app. Once logging is an unbreakable habit (after 6+ months), you can explore apps.
For the first 3-6 months, track only the exercise name, weight, and reps. This is all you need. Once you're consistent, you can consider adding a fourth metric like rest time between sets, but don't start there.
Track your reps and sets. To apply progressive overload, you have a few options: add more reps, add more sets, slow down the tempo (e.g., a 3-second descent on a push-up), or move to a harder variation, like from knee push-ups to full push-ups.
Increase the weight only when you can hit the top end of your target rep range for all your sets with good form. For example, if your goal is 3 sets of 8-12 reps, wait until you can do 3 sets of 12 reps before moving up by 5 pounds.
It's less critical than logging strength work, but it's a good habit. For cardio, track two things: duration and distance (or resistance level on a machine). Your goal is to go a little farther in the same amount of time, or the same distance in less time.
