Smolov: the Russian squat cycle that can add 100 pounds in 13 weeks
Smolov is the most brutal squat specialization program in common use. Here is how the thirteen weeks are structured, who it is actually for, and what it takes to survive it.
What Smolov is
Smolov is a thirteen-week squat specialization cycle attributed to Sergey Smolov, a Russian master of sport. It reached English-speaking lifters through Power to the People Professional in 2001 and has been passed around ever since on the strength of a single claim: a hundred pounds on your back squat in a little over three months.
That claim is not marketing. It happens. What gets left out is that it happens to lifters who meet the prerequisites, eat like it is a job, and do not miss sessions.
Who should not run it
Smolov is not a beginner program, and running it early is the most common way people get hurt on it.
- Less than a year of consistent barbell training
- A back squat under roughly 300 lb
- Squat technique that breaks down under fatigue
If any of those apply, build a base first. Wendler 5/3/1, a 5×5, or Madcow will add weight to your squat with a fraction of the recovery cost, and you will get more out of Smolov later.
The four phases
Weeks 1–2: Introduction
Prepares the quads, glutes and hamstrings for what is coming. You squat three days in a row working up to heavy singles, with the rest of the week given over to stretching and recovery. In week two you move to every other day.
Weeks 3–6: Base
The volume block, and the part people quote. You squat four times a week:
- Monday: 4 sets of 9
- Wednesday: 5 sets of 7
- Friday: 7 sets of 5
- Saturday: 10 sets of 3
Weight goes up every session and again every week. Week four backs off to a single squat session and a PR attempt.
Weeks 7–8: Switching
A two-week deload. It looks optional. It is not: the intense phase assumes you arrive recovered.
Weeks 9–13: Intense
Squatting drops to three days a week, but 44% of the work sits between 81% and 90% of your one rep max. Most lifters who have run the full cycle name this as the hardest stretch. Week five of the block is where you attempt the new PR.
What makes it work
Smolov succeeds or fails on recovery, not on effort. The programming is fixed; everything you control sits outside the gym.
- Do not deadlift. Pulling heavy during the full cycle competes directly with the squat work and blunts both.
- Eat aggressively. Around 4,000 kcal a day depending on bodyweight. Under-eating on Smolov does not produce a slower result, it produces a stalled one.
- Sleep eight hours minimum. This is where the adaptation actually happens.
- Stretch on rest days. It reduces injury risk and shortens the time between sessions when you can move properly again.
- Find a training partner. Week ten at 8am on a Saturday is not a solo activity.
Smolov Jr.
If thirteen weeks of squatting four times a week is more than you want to commit to, Smolov Jr. is the three-week base block run on its own. It is the version most lifters should start with. It delivers a meaningful jump, it fits inside an existing program, and it tells you honestly whether you can tolerate the full cycle.
Running the numbers
The arithmetic is the tedious part. Every session has its own percentage, every week shifts, and getting it wrong by 5% compounds across the cycle. The Smolov app calculates the weight for every set, runs the rest timers, handles Smolov Jr. cycles, and tells you which plates to load. It is free on iPhone and Android.
