How to track strength gains: the 5 numbers that actually matter

Most lifters track too many numbers. The ones that actually matter come down to five.

Track these and you can answer the only question that counts. Is the training working?

1. The estimated one rep max for your main lifts

The 1RM is the heaviest weight you can lift once with technique that holds up. It is the language strength training is written in. Every working set is a percentage of it.

You do not need to actually max out to know your 1RM. Estimate it from a heavy working set using the Epley formula. Weight times one plus reps times 0.0333. A set of 5 at 80kg returns an estimated 1RM of around 93kg. The free one rep max calculator runs three formulas and averages them, so you do not have to do the maths.

Track the estimated 1RM for the four lifts that build the structure. Squat. Bench press. Deadlift. Overhead press. If dumbbells are your main pieces of kit, swap to dumbbell goblet squat, dumbbell bench press, single-leg Romanian deadlift and dumbbell overhead press. The lifts change. The principle does not.

Plot the four numbers weekly. If three of the four are climbing, training is working. If two have stalled you are due a deload. If all four have flatlined the programme is wrong or your recovery is broken.

2. Total weekly volume per muscle group

Volume is sets times reps times weight, totalled across the week, broken down by muscle group. It is the second number to track because it tells you whether you are doing enough work to drive an adaptation, or too much to recover from.

For most adults over 40, weekly volume sits somewhere in this range per muscle group.

Legs: 10 to 14 working sets per week.

Back: 10 to 14 working sets per week.

Chest: 8 to 12 working sets per week.

Shoulders: 8 to 12 working sets per week.

Arms: 4 to 8 working sets per week, plus the work they get from rows and presses.

If your 1RMs are climbing and your weekly volume sits in those ranges, you are doing the right amount of work. If your 1RMs are not climbing and your volume is at the top of those ranges, the problem is recovery, not training. If your 1RMs are not climbing and your volume is at the bottom of those ranges, the answer is to add a set per session.

3. Sleep duration and consistency

This is the one most lifters do not log and most coaches put first.

Track average hours of sleep per night across the week and your bedtime consistency. If your average drops below seven hours for two weeks in a row, strength will not climb no matter what your programme says. Sleep is when the adaptation happens. Without it the rest is wasted.

A simple weekly log works. Bedtime, wake time, total hours, one to five for quality. Look at it monthly. If sleep is the variable that changed when training stalled, you have your answer.

4. Bodyweight, weekly average

Not daily weight. The daily reading bounces by two kilos based on water and food. The weekly average is the signal.

For strength training the bodyweight you want depends on the goal. If the aim is to get stronger without changing how you look, hold within a kilo of your starting weight. If the aim is to build muscle, bias the diet up by 200 to 300 calories a day and expect the weekly average to climb 0.2 to 0.4 kilos. If the aim is to drop body fat while preserving strength, bias the diet down by 250 to 500 calories a day and expect the average to fall by 0.4 to 0.7 kilos.

Weigh in three to seven mornings a week, take the average, plot it weekly. Bodyweight matters because it sets the context for what those lifting numbers mean. A 10 percent bench press increase at the same bodyweight is real progress. A 10 percent increase while gaining six kilos is partly progress and partly leverage.

5. Subjective readiness

The last number is a daily self-rating, one to five. Five means snappy and ready to lift heavy. Three means normal Tuesday. One means the joints ache and the sleep was poor.

The readiness rating is not for one session. The signal is the trend across two weeks. If the average has dropped a full point and the lifts are stalling, you are deep into accumulated fatigue and a deload is overdue. If the readiness is high and the lifts are climbing, you are in the part of the block where personal records happen and you should push.

A daily rating takes five seconds. Most strong lifters keep one in some form. Inside the STRNTH app it shows up as green, amber and red signals and feeds the coach's session recommendations. On paper it lives as a single column on the back of a notebook. Either works.

What to ignore

Workout streaks. They reward showing up, which is good, but they punish the rest days the body needs. Plenty of strong lifters take Sundays off forever.

Calories burned per session. A strength session burns far fewer than the wearable tells you. Strength training does its body composition work between sessions, through muscle mass that raises basal metabolic rate around the clock.

Single-set personal records on auxiliary lifts. A barbell curl PR is a fun day. It is not signal about whether your training is working.

Average heart rate during sets. Strength training is a CNS sport, not a cardio one. Heart rate during a heavy double does not tell you anything useful.

Anything on a leaderboard you did not consent to be on.

How to look at the five numbers together

Monthly review. Pull the five numbers for the last 4 weeks.

If three of four 1RMs are climbing, volume is in range, sleep is consistent at seven to nine hours, bodyweight is moving in the right direction and readiness is steady or rising, do not change anything. Keep training.

If your 1RMs have flatlined, volume is in range, sleep is solid and readiness is dropping, take a deload week. The body is asking.

If your 1RMs are climbing but sleep is dropping, you are buying short term progress on borrowed recovery. Fix the sleep before the bill arrives as a niggle.

If nothing is climbing for three months and the other numbers look fine, your programme is wrong. Switch to one that is structured for your level. The programmes page lists options that build on each other.

Where STRNTH handles this automatically

Inside the STRNTH app the 1RM estimate updates after every working set, weekly volume is broken down by muscle group, the STRNTH Index gives you one number for overall strength and the recovery signals show you green, amber or red readiness based on your real history. Body composition tracking lives in the same app. The five numbers all sit in one view.

If you would rather log the numbers by hand, the principle still applies. The point is to track signal, not noise. Five numbers, plotted weekly, reviewed monthly. That is enough.
