How to run the Ivysaur 4-4-8 program
Contents

Based on u/lvysaur's beginner program, posted to r/Fitness in 2016, with some minor adaptations.

A three day full body barbell program written as a direct answer to Starting Strength and StrongLifts. The author's argument was that both squat too much relative to everything else, give the bench and the deadlift too little, never vary the reps, and have no way to progress faster than their one fixed rate. This program fixes all four, and the fix for the last one is the best thing in it: hit eight or more on your AMRAP set and your increase for that lift doubles.

Who Is This Program For?

Ivysaur 4-4-8 is for the beginner or returning lifter who wants a barbell linear progression with more balance and more rep variety than the classics.

It suits you if:

  • You are in your first year of barbell training, or coming back after time off
  • You can train three days a week with a rest day between sessions
  • You want your bench and deadlift to move as fast as your squat
  • You would rather the program adapt to how fast you are actually progressing

It is a beginner program in the sense that it adds weight on a schedule. If you can no longer add weight every two weeks, move on to something with a longer cycle.

The Argument With Starting Strength

ComplaintWhat this program does
Too much squattingSquat three times per two weeks, not nine
Not enough benchBench in every single session
Not enough deadliftDeadlift three times per two weeks, heavy and light
No rep variationEvery lift alternates sets of four and sets of eight
One fixed progression rateThe AMRAP set doubles your increase when it goes well

Program Structure

Two Weeks, Not One

The cycle is six sessions long, not three. Week A and week B are different, so what you do on a Monday depends on which week you are in.

Every session is four exercises: one horizontal press, one lower body compound, one overhead press, one upper back pull.

Week A

ExerciseDay 1Day 2Day 3
Bench Press4 × 44 × 83 × 4 + 1 × AMRAP
Squat4 × 83 × 4 + 1 × AMRAP
Deadlift4 × 4
Overhead Press4 × 84 × 44 × 8
Chin Up4 × 84 × 4
Bent Over Row4 × 8

Week B

ExerciseDay 1Day 2Day 3
Bench Press4 × 84 × 44 × 8
Squat4 × 8
Deadlift4 × 83 × 4 + 1 × AMRAP
Overhead Press4 × 44 × 83 × 4 + 1 × AMRAP
Chin Up4 × 8
Bent Over Row4 × 44 × 8

Monday, Wednesday, Friday with at least one rest day between sessions.

One Weight Per Lift

The eight rep weight is 90% of the four rep weight. You have one number per lift and everything else comes out of it.

Your squat four rep weight is 100 kg / 225 lbs
  4 × 4 days: 100 kg / 225 lbs
  4 × 8 days:  90 kg / 200 lbs

That is the whole loading model. There is no percentage of a max anywhere in this program.

Progression: The Part That Makes It Different

Each lift increases once per two week cycle, off its AMRAP set.

LiftBase increaseIf the AMRAP hits 8+
Squat, Deadlift7.5 kg / 15 lbs15 kg / 30 lbs
Bench Press, Bent Over Row5 kg / 10 lbs10 kg / 20 lbs
Overhead Press2.5 kg / 5 lbs5 kg / 10 lbs
Chin Up1.25 kg / 2.5 lbs after every two clean sessions

The AMRAP is the whole mechanism. Four of the lifts carry one AMRAP set per cycle, on the third day of the week they are heaviest in. Three sets of four, then a fourth set taken for as many reps as you can with good form.

  • Get four or five: normal increase
  • Get eight or more: double the increase

That is the answer to the "one fixed progression rate" complaint. A beginner whose squat is flying gets 15 kg a cycle instead of 7.5, and gets it because they earned it rather than because a program guessed.

The bent over row and the chin up have no AMRAP: the row takes the base increase every cycle and the chin up adds the smallest plate you have after every two clean sessions.

When You Miss

If you cannot complete the sets, cut that lift by 10% and build back. Only that lift, and only when you have missed it repeatedly rather than after one bad day.

Everything else in the program carries on untouched. A bad squat cycle does not touch your bench.

Get Your Form Right First

Everything below assumes your form is already solid. Finding your working weight, adding weight, chasing reps, all of it only works if you can perform the lift correctly. While your form is not locked in, that is your only job. Make good form the goal of every set, not the weight on the bar. Drilling the movement with an empty bar beats loading plates onto a lift you cannot control yet.

To learn, don't hesitate to search Google and YouTube (there is a lot of good free material) and record yourself from the side to compare against a proper demonstration. In general, good form means a full controlled range of motion, a braced neutral spine, no bouncing or momentum, a consistent setup every rep, and ending the set when technique breaks down rather than grinding sloppy reps.

Finding Your Starting Weights

You enter one weight per lift: the weight you can take for four clean sets of four.

Not your four rep max. A weight you can do four sets of four with, which is meaningfully lighter.

If You Have Never Trained

Start with the empty bar on everything and let the increases do the work. Two weeks in you will have added 15 kg to your squat and it will still be easy, which is exactly what you want from a first month.

If You Are Coming Back

  1. Take the heaviest weight you have used recently for a set of five
  2. Use about 85% of it as your four rep weight
  3. Round down

Example:

You squatted 120 kg / 265 lbs for 5 a few months ago:
  Four rep weight = 120 × 0.85 = 102, round to 100 kg
                  = 265 × 0.85 = 225 lbs
  Eight rep weight = 90 kg / 200 lbs, worked out for you

Start light on purpose. The increases here are large, up to 15 kg a cycle on the squat, so a conservative start is caught up with inside a month. A greedy start is not.

Warming Up

SetWeightReps
1Empty bar8
2~40% of the working weight5
3~60% of the working weight3
4~80% of the working weight2

Ramp before the first exercise of each pattern. The eight rep days need less than the four rep days, because the weight is lower and the first working set does part of the job.

Rest Times

SituationRest
Deadlift4 minutes
Squat3 to 3.5 minutes
Bench Press, Overhead Press3 minutes
Before the AMRAP set3 minutes
Rows, Chin Ups2 minutes

Rest fully before an AMRAP set. It sets your increase for the next two weeks, and rushing it costs you a doubled increase you had earned.

When Things Go Wrong

If you miss reps on a four rep day, finish what you can and try the same weight next cycle. One bad session is not a stall.

If you miss the same lift for three cycles, cut it 10% and rebuild. Only that lift.

If an eight rep day is a fight, your four rep number is too high. The eight rep work is at 90% of it and it is supposed to be completable.

If your AMRAP never gets past five, that is fine and normal. The doubling is a bonus for lifts that are flying, not a target.

If everything stalls at once, take a light week at two thirds of the weight and then restart the cycle where you left off.

Program Duration

The program runs until it stops working, which for a genuine beginner is several months and often close to a year.

There is no fixed block and no scheduled deload. When two or three lifts need a 10% cut in the same month, the program has run its course and you should move to something with a longer cycle: the Texas Method, GZCLP or a 5/3/1 variant.

A third-party version of this program adds a fixed ten week block with a deload in week 5 and a PR week in week 10. That is not the original and is not what is written here.

Run Ivysaur 4-4-8 on Virtus Athlete

The two week cycle and the 90% volume weight are the two things people get wrong in a notebook. Virtus Athlete tracks which week you are in, works out every eight rep weight from your four rep number, and doubles your increase the moment an AMRAP set clears eight, so the fastest part of the program happens without you having to remember it.

Free on iOS and Android.

Frequently Asked Questions (FAQ)

Why is the cycle two weeks?
Because the exercise distribution does not fit in one. Bench appears every session, squat three times per two weeks and deadlift three times, and getting that balance with three sessions a week takes six sessions to complete.
Do I really squat only three times per two weeks?
Yes, and that is the point of the program. Starting Strength squats nine times in the same period, which the author argued crowds out everything else.
What if I get eight reps on the AMRAP every single cycle?
Then you keep doubling and your lifts move very fast, which is what should happen to a beginner who is recovering well. It will stop on its own.
Can I add arm work?
Yes, at the end of a session, two or three sets. Nothing that compromises the next session.
Why does the row have no AMRAP?
Because rows are hard to judge honestly at high reps: form drifts before the muscles give out. It takes the base increase every cycle instead.
Should I take the AMRAP set to failure?
Stop one rep short of it. The rep count decides your next two weeks, so a rep you barely completed with a rounded back is buying an increase you cannot use.
What about chin ups if I cannot do four?
Use an assisted machine or bands and enter zero added weight. Add the belt when four sets of four at bodyweight is comfortable.
What comes next?
The Texas Method or GZCLP. Both move from a weekly or per-session increase to a longer cycle, which is what you need when two weeks stops being enough time to recover and adapt.
