What Numbers in My Workout History Show Patterns in My Strength Over the Last 6 Months

The One Number That Reveals Your True Strength (It's Not Max Weight)

To figure out what numbers in my workout history show patterns in my strength over the last 6 months, you need to stop looking at random data points and focus on one metric: your Estimated 1-Rep Max (e1RM). You're probably staring at a notebook or spreadsheet filled with dates, weights, and reps, feeling completely lost. One week you bench 185 pounds for 5 reps, the next you hit 190 for only 3. Are you stronger? Weaker? It’s impossible to tell. This confusion is why most people who work out consistently for years still feel like they're spinning their wheels. They have data, but not information.

The solution is to translate every top set you perform into a single, comparable number. Your e1RM is a calculation that predicts the maximum weight you could lift for a single repetition, based on the weight and reps you actually performed. It’s the great equalizer. It turns messy data into a clear trend line.

Here’s a simple formula to calculate it:

Weight Lifted / (1.0278 – (0.0278 × Reps)) = e1RM

Let’s make this real. Imagine these two squat sessions from your log:

• Month 1: You squatted 225 pounds for 8 reps. Your e1RM was 281 pounds.
• Month 3: You felt tired, dropped the weight, but pushed harder. You squatted 205 pounds for 10 reps. Your e1RM was 275 pounds.
• Month 6: You squatted 245 pounds for 6 reps. Your e1RM is 293 pounds.

Without the e1RM, this looks like random progress. With it, you have a clear story: You had a slight dip in month 3, but over the full 6 months, your squat strength trended up by 12 pounds. That is real, measurable progress. This is the number that separates guessing from knowing.

Stop guessing if you're getting stronger.

Track your lifts in one place. See your strength grow week by week.

Why “Progressive Overload” Is a Lie Without This Metric

You’ve heard the term “progressive overload” a thousand times. It means doing more over time-more weight, more reps, more sets. But just adding things randomly isn't a plan. It’s chaos. The real goal of progressive overload is to increase your strength potential, and the only way to track that accurately is with a metric like e1RM. Many people focus on a different number: total volume (Sets x Reps x Weight). While useful for tracking work capacity, it’s a terrible indicator of top-end strength.

For example:

• Workout A: 3 sets of 10 reps at 150 lbs = 4,500 lbs of volume.
• Workout B: 5 sets of 3 reps at 175 lbs = 2,625 lbs of volume.

Your volume in Workout B is almost 2,000 pounds lower, but you are clearly stronger. If you only tracked volume, you’d think you were going backward. This is why so many people get frustrated. They follow advice that tells them to chase volume, but their actual strength stalls.

The other failed approach is simply trying to add 5 pounds to the bar every week. This works for a few months if you're a beginner, but it always ends in a hard wall. Life isn’t linear. Some weeks you have bad sleep, high stress, or poor nutrition. You won’t be able to add weight, and you'll feel like a failure. But on those same days, you might be able to hit your previous weight for one extra rep. That’s a win. That’s a strength increase your e1RM would capture, but the “add 5 pounds” method would miss entirely.

You have the formula now. You can calculate your e1RM for any lift. But can you plot its trend over the last 24 weeks? Do you know if your deadlift e1RM is trending up by 2% per month or if it's been flat for the last 90 days? Knowing the formula is one thing; having the data organized to show you the pattern is the real challenge.

The 3-Step Audit to Map Your Last 6 Months of Strength

Ready to turn your messy workout log into a clear report card on your strength? This isn't complicated and doesn't require a degree in data science. You just need about 30 minutes and your workout history. This audit will tell you exactly what worked, what didn't, and where you're headed.

Step 1: Choose Your 3-5 Core Lifts

You can't-and shouldn't-track everything. It’s overwhelming and unnecessary. Pick the 3 to 5 compound exercises that are the foundation of your program. These are your Key Performance Indicators (KPIs) for strength. For most people, this will be some combination of:

• A Squat variation (e.g., Barbell Back Squat)
• A Pressing variation (e.g., Bench Press, Overhead Press)
• A Hinging variation (e.g., Deadlift, Romanian Deadlift)
• A Pulling variation (e.g., Barbell Row, Weighted Pull-up)

Don't overthink it. Choose the main lifts you've been doing consistently for the last 6 months. These are the pillars of your strength.

Step 2: Find Your Monthly “Top Set”

Go through your workout history, month by month, for each core lift. You are looking for one thing: the single best set you performed in that calendar month. This is your “top set.” It's the set where the combination of weight and reps would produce the highest e1RM. Ignore warm-ups and back-off sets. You are hunting for your peak performance for that 30-day period.

For example, in April, you might have done these bench press workouts:

• Week 1: 185 lbs x 5 reps
• Week 2: 175 lbs x 8 reps
• Week 3: 190 lbs x 3 reps

Let's calculate the e1RM for each: Week 1 = 211 lbs. Week 2 = 219 lbs. Week 3 = 205 lbs. Your top set for April was 175 lbs for 8 reps. That's the number you'll log for that month.

Step 3: Calculate and Plot Your e1RM Trend

Now, create a simple table for each core lift. List the 6 months and fill in the e1RM you calculated from your top set for each month.

Example: Deadlift Strength Audit

• Month 1: 315 lbs x 5 reps -> e1RM: 358 lbs
• Month 2: 325 lbs x 4 reps -> e1RM: 363 lbs
• Month 3: 315 lbs x 6 reps -> e1RM: 377 lbs (New Rep PR!)
• Month 4: 335 lbs x 3 reps -> e1RM: 362 lbs (Slight dip)
• Month 5: 345 lbs x 4 reps -> e1RM: 385 lbs
• Month 6: 350 lbs x 4 reps -> e1RM: 391 lbs

When you look at this data, the pattern is undeniable. Despite a small dip in month 4, your deadlift strength is clearly trending upward. You've added a calculated 33 pounds to your 1-rep max in six months. This is proof your training is working.

What Your Strength Pattern Predicts for the Next 6 Months

Looking at your 6-month trend line isn't just about validating the past; it's about predicting the future and making smarter decisions. The shape of that line tells you everything you need to know.

If Your Trend Line is Going Up:

This is the goal. A steady, upward-trending e1RM means your program, nutrition, and recovery are aligned. For an intermediate lifter, an increase of 1-2% per month (or 5-12% over 6 months) is fantastic progress. Don't change a thing. Your job is to continue executing the plan. What you're doing is working.

If Your Trend Line is Flat:

A flat line for more than 8 weeks is the definition of a plateau. It means your body has fully adapted to your current training stimulus. This is not a reason to panic; it's a signal that you need to change one key variable. You could switch your main lift (e.g., from barbell bench to incline dumbbell press for 8 weeks), change your rep scheme (e.g., from sets of 5 to sets of 8-10), or increase your total weekly volume.

If Your Trend Line is Going Down:

A downward trend for more than 4 weeks is a red flag. This is not a plateau; this is regression. It's almost always caused by one of two things: accumulating too much fatigue (overtraining) or not recovering enough (poor sleep, high stress, under-eating). The answer is not to train harder. The answer is to pull back. Take a deload week where you cut your volume and intensity by 50%. Prioritize getting 7-9 hours of sleep. Make sure you're eating enough calories and protein. Your body is waving a white flag, and you need to listen.

Progress is never a perfect, straight line. It will have peaks and valleys. Your goal is not to avoid the valleys, but to ensure the overall trend is moving up and to the right over a 6-month horizon.

Frequently Asked Questions

The Importance of Total Volume

While e1RM is best for tracking top-end strength, total weekly volume (Sets x Reps x Weight) is a key indicator for muscle growth (hypertrophy). If your goal is size, you should see your weekly volume for each muscle group trending up over time. Often, strength and volume will increase together.

What If I Don't Have 6 Months of Data?

Don't worry. Start today. For the next 4 weeks, diligently track your top sets for your chosen core lifts. At the end of 4 weeks, calculate your baseline e1RM for each. Your goal for the following month is simply to beat that number. You've just started your own 6-month history.

How Often to Calculate e1RM

You don't need to calculate it for every set of every workout. That's overkill. A simple and effective method is to calculate it once per week for the top set of each of your core lifts. This gives you a weekly data point to track your trend, which is more than enough information.

Strength vs. Hypertrophy Training Patterns

For pure strength, the e1RM trend is your north star. For hypertrophy (muscle growth), the pattern is a combination of a rising e1RM and a rising total volume. If your volume is going up but your e1RM is flat, you're building work capacity, which is a good foundation for future strength gains.

Dealing with Plateaus or Dips in the Pattern

A dip in your e1RM for 1-2 weeks is normal. It could be due to stress, a bad night's sleep, or a slight cold. Don't overreact. However, if your e1RM trend line is flat for 8 consecutive weeks, that's a true plateau. It's time to introduce a new stimulus, like changing exercises or rep ranges.
