You did the first part. You bought the notebook or downloaded the app. You wrote down your sets, reps, and the weight you lifted. Now you're staring at a list of numbers, wondering what it all means. It feels productive, but without a next step, it's just a diary of your gym sessions.
If you've just started tracking my workouts what do I do with the data, the simple answer is this: use it to beat your last performance. That's it. Your workout log isn't a historical document; it's a battle plan for your next session. The numbers you wrote down are the enemy to defeat next week.
This concept is called Progressive Overload. It's the single most important principle for building muscle and strength. Your muscles will not grow unless you give them a reason to. They adapt to the stress you place on them. If you lift the same 50-pound dumbbells for 8 reps every week, your body has no incentive to change. It has already adapted to that load.
Tracking provides the objective proof you need to force adaptation. It removes the guesswork. You no longer walk into the gym and wonder, "What should I lift today?" You look at your log and know, "Last week I did 135 lbs for 5 reps. Today, my only job is to do 135 lbs for 6 reps."
Your data has one job: to tell you the bare minimum you need to do to make progress. Every other benefit-seeing how far you've come, staying motivated-is secondary to this primary function. You are collecting intelligence on your past self to ensure your future self is stronger.

Track your lifts in Mofilo. We'll show you what to lift next.
Most people who start tracking fall into the trap of passive data collection. They meticulously log every set and rep but never look at the data again. Or they glance at it but have no system for making decisions. This is the equivalent of tracking your spending without ever creating a budget. It's information without action.
Without a plan, your workouts become random. One week you feel good, so you add 20 pounds to your squat. The next week, you feel tired, so you drop the weight. There's no consistent, upward pressure. This leads to stagnation, which is the #1 reason people get frustrated and quit.
They think, "I'm going to the gym and tracking my workouts, but I'm not getting stronger." The problem isn't the tracking; it's the absence of a system to interpret the data.
Your workout log should not be a record of what you *did*. It should be a prescription for what you *will do*. The real work happens in the 5 minutes before your workout when you review last week's numbers and set a concrete, non-negotiable target for today.
Stop being a historian of your workouts. Start being an architect of your progress. The data tells you where the next brick goes.
This is the system. It's simple, takes less than five minutes, and guarantees you're applying progressive overload. Do this before each workout.
Before you start your chest day, open your log to last week's chest day. Look at the first exercise. Let's say it was Barbell Bench Press, and you logged: 135 lbs for 3 sets of 8 reps (3x8).
This is your baseline. Your mission for today is to beat "135 lbs, 3x8."
The "Two-Rep Rule" is the simplest way to know when to increase the weight. It works like this:
If your rep target for a set is 8 reps, and you successfully complete 10 reps (2 more than the target) on your *final* set, you have earned the right to increase the weight in your next session.
Let's use our example. Last week, your goal was 3 sets of 8 reps at 135 lbs. On your third and final set, you felt strong and pushed out 10 reps. Because you hit 2 reps over your target, you now know that for this week's workout, you will not be using 135 lbs. You will be using more.
How much more? For big compound lifts like squats, deadlifts, and bench presses, add 5 pounds. For dumbbell exercises or isolation movements like bicep curls, add 2.5 to 5 pounds.
Based on Step 2, you now have a clear plan. You will write down your new goal *before* you even touch the bar.
Last Week: Bench Press: 135 lbs - 8, 8, 10
Today's Goal: Bench Press: 140 lbs - 3 sets of 8 reps (3x8)
Your entire focus for that exercise is hitting the new target. Maybe you only get 8, 7, and 6 reps with the new weight. That's a win. You successfully overloaded your muscles with a heavier weight. Your new baseline to beat next week is now "140 lbs, 8, 7, 6."
This simple, three-step process turns your abstract data into a concrete, actionable plan for guaranteed progress.

Every workout logged. See the proof that you are getting stronger week by week.
Eventually, you will hit a wall. You won't be able to add 5 pounds to the bar every week. This is normal and expected. It doesn't mean you've failed; it means it's time to use other methods of progressive overload that your workout data makes possible.
When you can't increase the weight, your goal is to increase the total volume in a different way. Here is the hierarchy of what to do when you're stuck.
This is the most straightforward alternative. If you benched 140 lbs for 8, 7, 6 reps last week, your goal this week is to bench 140 lbs for 8, 8, 7 reps. You are still beating your past self. You are still creating a new stimulus for growth. Continue adding reps each week until you can hit your original rep target (e.g., 3 sets of 8) with that weight. Once you do, you can try increasing the weight again.
Let's say you're stuck at 140 lbs for 3 sets of 6 reps and you just can't seem to get that 7th rep. Instead of trying to add reps, add another set. This week, your goal is to do 4 sets of 6 reps at 140 lbs. You've significantly increased the total work your muscles have to do, forcing a new adaptation.
This is a more advanced technique. If you normally rest 90 seconds between sets, your goal for this workout is to rest only 75 seconds. By reducing rest, you are increasing the metabolic stress on the muscle and forcing it to work more efficiently under fatigue. You performed the same work in less time, which is a form of progress.
Your workout data is what allows you to make these strategic decisions. Without it, you're just guessing. With it, you always have a clear path forward, even when adding weight isn't an option.
Review your data for a specific workout immediately before you do that same workout again. If you do a chest workout on Monday, you should review last Monday's numbers right before you start this Monday's session. This keeps the targets fresh in your mind.
Don't panic. A single bad workout is just a blip. It could be due to poor sleep, stress, or nutrition. If your numbers dip, your goal for the next session is simply to get back to where you were the week before. Only worry if you see a consistent downward trend for 3-4 weeks in a row.
For barbell compound exercises like squats, deadlifts, and bench press, increase by 5 pounds total. For dumbbell exercises, increase by 2.5 or 5 pounds per dumbbell. For machine or isolation exercises, go up by the smallest increment possible, which is usually 5-10 pounds.
No. A simple $1 notebook and a pen work perfectly. The tool doesn't matter as much as the system you use. The goal is consistency, not complexity. Start with a notebook, and if you find you need more features later, you can explore apps.
No, only track your main "working sets." These are the challenging sets you perform after you've warmed up. Tracking warm-up sets adds unnecessary clutter to your data. Focus on logging the sets that are actually meant to stimulate muscle growth.
