Linear periodization training: how it works and who it's for

Linear periodization key numbers

Linear periodization is a plan spanning a few months in which the load goes up and the reps per set go down about every 4 weeks.

Phases of linear periodization

Linear periodization has three phases, each a separate mesocycle, and the last week of the cycle is a test.

The last phase uses loads of 80% of 1RM and above, because with such loads strength went up more (the 2026 ACSM position stand). The model was described by the Soviet theorist Lev Matveyev and developed further by Stone and Bompa, among others (Lorenz et al. 2010). The name is a little misleading, because after the test the cycle starts over from a higher point (Evans 2019).

When to choose linear periodization

Linear periodization, like other models of training periodization, won't build more muscle than a regular plan in which you add weight or reps. It helps when the goal is strength on a specific day, e.g. a 1RM test or a meet.

How to set up linear periodization step by step

1. Pick 2-4 barbell lifts you want to get stronger in, e.g. Barbell Squat, Barbell Bench Press or Deadlift.
2. Instead of maxing out, estimate your 1RM from your last heavy set in the 1RM calculator in RIR/RPE mode: 85 kg × 5 at RIR 1 is about 100 kg.
3. Split the 12 weeks into 3 phases of 4 weeks: 10, 6 and 3 reps per set.
4. Within a phase, add 2.5% of 1RM each week if your first set left as many reps in reserve as the table below shows; if it left 1 or more fewer, repeat the load the following week. Make the fourth week of phases 1 and 2 lighter: half the sets with the load from the phase's first week.
5. Keep 4-5 sets per lift in every phase and train each lift twice a week, the deadlift once.
6. In weeks 11-12, do 30-50% fewer reps than in week 10 (in week 11 with a load about 5% of 1RM higher), and test at the end of week 12.

The smallest plates are usually 1.25 kg, so the bar goes up in 2.5 kg steps, exactly 2.5% with a 100 kg 1RM. With an 80 kg Barbell Bench Press 1RM, 2.5% is 2 kg, so weeks 2 and 3 both come out at 55 kg, and in week 3 you add a rep instead of weight.

Do the Deadlift once a week and for fewer reps, e.g. 4 × 6 at 75%, 4 × 4 at 80% and 4 × 2 at 87.5% of 1RM at the start of the phases, because at 10 reps your grip and lower back tire before your legs do and technique breaks down. With 4 sessions a week, you do Lower A with the heavy squat and the Romanian Deadlift, Upper A with the heavy bench press, Lower B with the lighter squat and the Deadlift, and Upper B with the lighter bench press. Strength went up more when a lift was trained more often (Pelland et al. 2025, the 2026 ACSM position stand).

12-week linear periodization example in kg

The example writes out 12 weeks of the Barbell Squat with a 1RM of 100 kg, so kilograms equal percentages of 1RM. RIR refers to the first set and comes from the same %1RM table as the RIR/RPE calculator; the reserve shrinks on the following sets.

The table is an average: the number of reps at a given %1RM depends on the exercise, and roughly one person in three is more than 2.5 reps off the average (Nuzzo et al. 2024). If your first set in week 1 leaves at least 2 reps more or fewer in reserve than the table, recalculate your 1RM from that set and redo the plan.

In weeks 3 and 7 the last set will end close to failure: if the second-to-last set leaves fewer than 2 reps in reserve, do 1-2 fewer reps on the last one.

Muscle grows more the closer to failure you end a set (Robinson et al. 2024), so a set of 3 reps with 3 in reserve does less for muscle than 10 reps at RIR 1-2. That's why in the strength phase, muscle growth comes mainly from accessory exercises at 8-15 reps.

The second, lighter squat session of the week is an element of undulating periodization: the same sets and reps with a load about 10% lower (in week 3: 62.5 kg), and in week 12 that session is the test.

Test in a rack with the safety bars set a few centimeters below the bottom of your squat. After a warm-up following the scheme from the 1RM calculator, make 2-3 single attempts 3-5 min apart: about 95 kg, then 100 kg, and 102.5-105 kg only if the previous one moved fast. Without maxing out, you can get your new 1RM in the calculator from a single AMRAP set with 85 kg.

You calculate the next cycle from the new 1RM: at 102.5 kg, week 1 is 4 × 10 with 67.5 kg. If your 1RM didn't go up, repeat the cycle with the same loads or switch to undulating periodization.

Linear vs undulating, block periodization and linear progression

Linear periodization vs linear progression

Linear progression is a fixed weight step from session to session at the same reps, e.g. +2.5 kg on the squat, as long as the weight keeps going up. Linear periodization is a plan that spreads progress over time: about every 4 weeks it changes the rep range and the load.

Reverse linear periodization

Reverse linear periodization goes the other way: it starts with heavy, low-rep sets and ends with lighter, higher-rep ones (Evans 2019). It was studied mainly for muscular endurance, and in a 15-week study with 60 people the difference from linear was not significant (Rhea et al. 2003).

Common mistakes

1. A 1RM from a good day. A record from six months ago or from a shallow squat inflates every percentage, and the plan falls apart in weeks 3 and 7. Base the percentages on a 1RM estimated from a set in the last 2-3 weeks.
2. Fewer sets in the strength phase. If your goal is muscle, dropping below MEV in the heavier phases can stall growth, because muscle grows with the number of sets (Pelland et al. 2025). Keep accessory exercises in every phase and run them with double progression.
3. Failure on heavy sets. In a squat at 90% of 1RM, failure risks losing control of the bar, and training to failure did not consistently give better results (the 2026 ACSM position stand). End heavy sets at RIR 1-2.
4. Sticking to the plan on a bad day. Sticking to the percentages after a sleepless night or while sick ends in missed sets. On a weak day, do your sets with the previous week's load.

What the research says

Studies compare linear periodization with undulating periodization and with a non-periodized plan, usually at the same number of sets; the certainty ratings are our assessment.

It's unknown whether several linear cycles in a row give more than the same amount of time with regular progression: no periodization study lasted longer than 9 months (Afonso et al. 2017), and untrained people dominated the comparisons of linear and undulating periodization.

What SmartWorkout logs show

A falling rep target, which linear periodization is built on, shows up in longer plans as often as a rising one, and most plans repeat a single week. If your goal is muscle, that's enough as long as you add weight or reps. Every number is based on at least 50 people.

How to set up linear periodization in SmartWorkout

You can set up linear periodization in SmartWorkout in the plan builder: each phase as a block, and each week with its own %1RM.

1. On the Workout tab, tap “See All” next to “My Plans”, then “+” and “Create new plan”.
2. Tap “Select load indicator” and choose “1RM”. There is one indicator for the whole plan, so accessory exercises get only a rep range, and you enter their target RIR in their “Tips”.
3. Tap “Add Block” > “Create mesocycle”, choose the number of sessions per week, add exercises and set “Number of weeks” to 4.
4. On the “Define Mesocycle” screen, enter the sets and the lift's %1RM for each week: 65, 67.5 and 70%, and in week 4 half the sets at 65%. In the second squat session, enter 10% less, e.g. 57.5, 60 and 62.5%.
5. Name the block after the phase (“Edit Block Name”, e.g. “Phase 1: 4 × 10”), clone it (“Clone”) for phases 2 and 3, and change the reps and percentages in them.

The mesocycle generator doesn't raise the percentages by itself. You log the week 12 attempt on the Workout tab as a “One Rep Max Test”.

With Premium, the plan's volume analysis shows the sets per muscle group in each week against the volume zones, so you can see whether cutting accessory exercises in the strength phase drops you below MEV.
