Ivysaur 4-4-8

A popular Reddit beginner program designed to fix the weaknesses of Starting Strength and StrongLifts 5x5. Three days per week across a 2-week rotating cycle, alternating between heavy sets of 4 and lighter sets of 8 for every lift. AMRAP sets every other week determine progression speed — hit 8+ reps and you double the weight increase.

Origin & Philosophy

The Ivysaur 4-4-8 program was created by Reddit user /u/lvysaur and posted to r/Fitness in 2016. The post was a detailed critique of Starting Strength and StrongLifts 5x5, arguing that both programs have structural flaws: too much squatting relative to other lifts, not enough bench press or deadlift volume, no rep variation, and no built-in mechanism to adjust progression speed.

The 4-4-8 name refers to the rep scheme: exercises alternate between sets of 4 (heavier, strength-focused) and sets of 8 (lighter, hypertrophy-focused). This undulating approach gives beginners exposure to both heavy and moderate loads, building strength and muscle simultaneously rather than relying on a single rep range.

Who It's For

• Experience: Complete beginners or lifters returning after a long layoff
• Goal: Build strength in all major barbell lifts while getting more bench press and deadlift volume than typical beginner programs
• Works on any diet: Beginners gain strength on a caloric deficit, though a slight surplus will accelerate progress

Pros & Cons

Pros

• Bench Press trained every session (3x/week) — more pressing volume than Starting Strength or StrongLifts
• Deadlift trained 2-3x per 2-week cycle instead of once — addresses the biggest gap in StrongLifts
• AMRAP sets auto-regulate progression: if you're advancing fast, the program doubles your weight jumps; if you're struggling, you progress at the base rate
• Alternating 4-rep and 8-rep days develop both strength and muscle, not just one
• Chin Up included for direct bicep work, which Starting Strength and StrongLifts both lack

Cons

• No isolation accessories — if you want direct arm, lateral delt, or ab work, you'll need to add your own
• Aggressive progression rates (up to +30lb/cycle on squat) mean beginners may stall within 6-8 weeks
• The 2-week rotating cycle is slightly harder to track than a simple A/B alternation
• Squat frequency is lower (2x per 2-week cycle) than in Starting Strength/StrongLifts (3x/week), which means less squat technique practice

Program Structure

• Split: Full body, 2-week rotating cycle
• Periodization: Weekly undulating — each exercise alternates between heavy (4-rep) and light (8-rep) sessions
• Rotation: Week 1 = Day 1/Day 2/Day 3, Week 2 = Day 4/Day 5/Day 6, then repeat
• The 8-rep weight is 90% of the 4-rep weight for each exercise

Bent Over Row	4x4	—	4x8

Exercise Selection & Rationale

Every session has 4 exercises: one horizontal press, one lower body compound, one overhead press variation, and one upper back pull.

Bench Press appears every session because the original author argued that StrongLifts and Starting Strength under-train the bench relative to other lifts. Squat and Deadlift rotate across sessions — when squat appears, Chin Up is the pull exercise; when deadlift appears, Bent Over Row is the pull. Overhead Press appears every session at the opposite rep scheme from bench (when bench is heavy, OHP is light, and vice versa).

Substitutions: Replace Chin Up with Lat Pulldown or band-assisted chin-ups if you can't do bodyweight reps. Bent Over Row can be swapped for Pendlay Row. No substitutions recommended for the main three lifts — learning Squat, Bench Press, and Deadlift is the point.

Set & Rep Scheme

Every exercise uses either 4 sets of 4 reps (heavy day, ~80% of 1RM) or 4 sets of 8 reps (light day, ~72% of 1RM). The 8-rep weight is approximately 90% of the 4-rep weight.

On Day 3 of each week, two exercises swap their last set for an AMRAP set (as many reps as possible): 3 sets of 4 + 1 AMRAP set. In Week 1, Bench Press and Squat get the AMRAP test. In Week 2, Overhead Press and Deadlift get it. This means every main lift gets tested once per 2-week cycle.

The alternation between 4-rep and 8-rep days serves a dual purpose: 4-rep sets build maximal strength (heavy loads, low reps), while 8-rep sets accumulate hypertrophy volume (moderate loads, more time under tension).

Progressive Overload

Weight increases are based on the AMRAP set performance each 2-week cycle:

Lift	Base increase per cycle	If AMRAP ≥ 8 reps
Squat / Deadlift	+15lb	+30lb
Bench Press / Bent Over Row	+10lb	+20lb
Overhead Press	+5lb	+10lb

The AMRAP serves as an auto-regulation mechanism: if you're advancing quickly and crush 8+ reps on the AMRAP, you get double progression. If you barely make the minimum, you progress at the standard rate.

On failure (can't complete all prescribed sets and reps): reduce weight by 10% and rebuild. Each exercise is tracked independently.

Chin Up progresses independently via linear progression — add 2.5lb of added weight after every two successful sessions.

How Long to Run It / What Next

Run for 3-4 months. The aggressive progression rates mean you'll eventually stall on most lifts. Signs it's time to move on: you're deloading frequently on 2+ lifts, your AMRAP sets barely hit 4, or you've been running it for 12+ weeks.

Good next programs:

• GZCLP — adds tiered exercise structure with more volume and a built-in stall protocol
• 5/3/1 for Beginners — slower, periodized progression that sustains progress longer
• Phrak's Greyskull LP — another beginner program if you want to stay in the LP phase but want a different structure

Equipment Needed

• Barbell, weight plates, squat rack, flat bench
• Pull-up bar or lat pulldown machine for Chin Up

Home gym substitutions: Replace Bent Over Row with Bent Over Row, Dumbbell if you only have dumbbells. Replace Chin Up with Inverted Row if you don't have a pull-up bar.

Rest Times

• Compound lifts on 4-rep days: 2-3 minutes between sets
• Compound lifts on 8-rep days: 90 seconds to 2 minutes
• AMRAP sets: Rest 3 minutes before the AMRAP set to maximize performance
• Chin Up and Bent Over Row: 90 seconds

How to Pick Starting Weights

The program uses 1RM percentages (80% for 4-rep days, 72% for 8-rep days). To set your 1RM in the app:

1. If you know your 1RM for each lift, enter it directly
2. If you don't, use the built-in 1RM calculator: find a weight you can lift for 5 clean reps, and the app will estimate your 1RM
3. If you're completely new, start with just the bar (45lb) for upper body lifts and 95lb for Squat and Deadlift, then adjust based on feel

Start lighter than you think. The progression rates are aggressive — you'll reach challenging weights within 3-4 weeks. Starting too heavy leads to early stalls and poor form.

Common Modifications

• Add accessories: After the main 4 lifts, add 2-3 sets of isolation work. Good picks: Face Pull for rear delts, Bicep Curl, Barbell for arms, Hanging Leg Raise for abs
• Can't do chin-ups: Use Lat Pulldown at 4x8-12 until you can do bodyweight reps
• Want more squat volume: Add 2 extra sets of Squat on deadlift days at the 8-rep weight
• 5 sets instead of 4: The original author noted you can do 5 sets if time permits for additional volume

FAQ

Is Ivysaur 4-4-8 better than Starting Strength or StrongLifts?

It addresses specific criticisms of those programs: more bench press volume, more deadlift work, rep variation, and auto-regulated progression via AMRAP sets. Whether it's "better" depends on your priorities — if you want more squat frequency, Starting Strength is the better choice. If you want balanced pressing and pulling, Ivysaur has the edge.

How many days a week is the Ivysaur 4-4-8 program?

It's a 3-day-per-week program with at least one rest day between sessions. A typical schedule is Monday/Wednesday/Friday. The program rotates through a 2-week cycle, so each week has a slightly different combination of exercises and rep schemes.

What does the AMRAP set mean in Ivysaur 4-4-8?

AMRAP stands for "as many reps as possible." On the third training day of each week, two exercises replace their last set with an AMRAP set. You do at least 4 reps, then keep going with good form. If you hit 8 or more reps, you double your weight increase for the next cycle.

How long should I run the Ivysaur 4-4-8 program?

Run it for 3-4 months maximum. The aggressive linear progression (up to +15lb per cycle on lower body lifts) means you'll eventually stall. When you're deloading frequently on multiple lifts, transition to an intermediate program like GZCLP or 5/3/1 for Beginners.

Can I add accessories to the Ivysaur 4-4-8 program?

Yes. The base program has no isolation work. After the main 4 lifts, add 2-3 sets each of exercises like face pulls, bicep curls, and hanging leg raises. Keep accessories light (10-15 reps) and don't let them interfere with recovery for the main lifts.

What if I can't do chin-ups on the Ivysaur 4-4-8 program?

Replace chin-ups with lat pulldowns at 4 sets of 8-12 reps, or use resistance band-assisted chin-ups. Work on these until you can perform bodyweight chin-ups for all prescribed sets, then switch to the programmed exercise.

What do I do when I stall on the Ivysaur 4-4-8 program?

When you fail to complete all prescribed reps on a lift, the weight automatically reduces by 10%. Use the lighter weight to rebuild and hit higher AMRAP numbers. Each lift is tracked independently, so stalling on bench doesn't affect your squat progression.

Why does Ivysaur 4-4-8 have less squatting than Starting Strength?

The original author argued that Starting Strength and StrongLifts over-emphasize squatting (3x/week) at the expense of other lifts, particularly the deadlift and bench press. Ivysaur 4-4-8 redistributes that volume: squats appear 2x per 2-week cycle, while bench press appears every session and deadlifts get 2-3 sessions per cycle.
