How to track progress in your training

Why log your training

The site's programs give the progression rules, but the decision to add weight is made from records, not memory. A week later “it felt easy” cannot be told apart from a real two reps in reserve, and without comparable records you cannot spot either growth or a plateau.

The log does three things:

• it fixes a starting point: the weight and reps you began at;
• it shows a trend: what happens to weight, reps and volume week by week;
• it separates progress from noise: a lucky session looks like a one-off, not like a “result”.

The log is local: paper, phone notes or the printed card above. No sign-up is needed, and the site stores nothing.

A minimal log template

Five columns are enough — the site's programs use the same template in their “How to keep a log” section, for example the 2-days-a-week beginner gym program:

The numbers in these rows illustrate the template, not recommended weights. If you train with one of the site's programs, the ready-made table is already in its “How to keep a log” section; if you follow your own plan, copy the columns.

Which metrics are worth tracking

Not every measurement is equally useful: metrics differ in how stable they are. The editorial team's practical rule is to compare a metric with itself, in the same way, over a suitable period:

Weight × reps is the main metric in strength training: it is recorded during the session and is tied directly to the progression rules. Volume is useful when you change the number of sets and want to see the week's overall picture.

Why short-term measurements are noisy

Short-term measurements almost always reflect the background, not the result of training:

• body weight changes by 1–2 kg over a day or two with water, salty food, portion size and sleep — the number is illustrative, and the range differs from person to person;
• the reps in a single session depend on sleep, rest and the order of exercises: “did less today” is often about last night, not about losing form;
• circumferences change depending on whether you measure after training or before, on an inhale or an exhale.

The practical rule: decide that progress exists or does not exist from a 2–4 week trend, not from a single record. A trap example: +1.2 kg on the scale on Monday after a weekend is mostly water and food, not two days of fat gain. Judging the result by that jump means measuring the wrong thing.

How to compare periods

• Window against window: the last 2–4 weeks against the previous 2–4, not “today against a best day”.
• The same exercise: compare leg press with leg press, not “a session with a session in general”.
• The same structure: with an equal number of sets you can see weight and reps rise; if the number of sets grew, volume rose by definition, and that is a separate line of comparison.
• One measurement method: the same scale and weighing time, the same measuring point — week to week.

If nothing changes for two weeks

A plateau is not a reason to change everything at once. Check in order:

1. Consistency: did every session of the last two weeks actually happen? Missed sessions are the most common explanation for a “stall”, with no physiology involved.
2. Sleep and recovery: chronic under-sleeping eats reps first.
3. Nutrition: a sharp calorie deficit and strength training combine poorly.
4. One variable at a time: add weight, or reps, or a set — and look at the next comparison window.

When this check finds no cause, go back to the load-increase rules: when exactly to add weight, reps or a set is covered in the guide How to progress your training load.

When the log is a stop signal

Records also capture stop signals. End the session rather than “finishing the set” if you feel dizzy, numb or sharp pain, or if your breathing does not recover within your usual rest. If pain does not pass or repeats session after session, that record is not “a plan for next week” but a reason to see a professional.

Limits of applicability

• This material is not medical advice: with health conditions, pregnancy or recovery from injury, discuss the method and frequency of measurements with a professional. With eating disorders, regular weighing may not be needed — that is also a professional's decision (the health boundaries of estimate calculations are in the daily-calorie calculator).
• A scale and a tape measure have error: compare records from one device and one method; scatter between devices is not a sign of progress or regression.
• The log does not measure technique: technique is judged from video or by the eyes of a knowledgeable professional, not from a “note” column.
• If the goal is simply “move more”, a full log is not required: a calendar of “trained / did not train” is enough.
• The numbers in this material's examples illustrate the template and are the editorial team's practical guidance, not a norm or a plan.

What next

The records answer “is there progress?”, and the double-progression rules answer “what to do about it”: when exactly to add weight, reps or a set is in the guide How to progress your training load. If one of your goals is changing body weight, a starting point for nutrition and the rule for adjusting by trend are in the daily calorie calculator. Ready-made plans with log tables built in are collected in the programs catalogue.
