5/3/1: Building the Monolith

Jim Wendler's most demanding 5/3/1 template — a 6-week mass-building block that pairs heavy 5/3/1 barbell work with extreme accessory volume (100+ reps of chin-ups, dips, and face pulls) and weekly widowmaker squat sets of 20 reps. Requires eating 1.5 lbs of ground beef and a dozen eggs daily. Not for the faint of heart.

Origin & Philosophy

Building the Monolith (BtM) was created by Jim Wendler as a finite 6-week hypertrophy block built on his 5/3/1 framework. Wendler — a former Westside Barbell lifter who squatted 1,000 lbs — designed it for lifters who were already strong but needed to get bigger.

The philosophy: combine heavy barbell work with extreme training volume and aggressive eating. Wendler mandates eating 1.5 lbs of ground beef and 12 whole eggs daily (~5,000+ calories). The program punishes you if you don't eat enough — you'll either grow or break. The name references Conan the Barbarian's approach to building something massive through relentless effort.

Who It's For

• Experience level: Intermediate to advanced (2+ years). You need solid technique on all four main barbell lifts because you'll be squatting heavy 3 days per week, including a 20-rep widowmaker set.
• Prerequisites: Comfortable with high-rep squatting. Able to do bodyweight Chin Ups and Chest Dips for multiple sets — Wendler recommends being able to accumulate 50+ dips and 50+ chin-ups in a session before starting.
• Primary goal: Hypertrophy with strength maintenance. Users commonly report 10-15 lbs of bodyweight gain and noticeable size increases in back, shoulders, arms, and quads over the 6 weeks.
• Best suited for: Aggressive bulking only. The extreme volume and mandated caloric intake make this incompatible with cutting or maintenance.

Pros & Cons

Pros

• One of the most effective short-term mass-building programs — 6 weeks of commitment produces visible results in back, shoulders, arms, and quads
• Squat trained 3x/week (heavy 5x5 Monday, ramp-up Wednesday via Deadlift day, widowmaker Friday) drives rapid leg growth
• 100-rep accessory sets for Chin Ups, Chest Dips, and Face Pulls build serious upper body size without complicated exercise selection
• Only 3 training days per week, leaving room for conditioning and recovery
• Finite 6-week duration provides a clear endpoint — you can push harder knowing it's temporary

Cons

• Sessions run 90-120+ minutes due to sheer volume — the 100-rep accessory sets alone take 15-20 minutes each
• Recovery demands are extreme — requires ~5,000+ calories daily, quality sleep, and 3-4 conditioning sessions per week
• The 20-rep widowmaker squat sets are mentally and physically brutal, especially in weeks 5-6 when the weight reaches 55-60% of 1RM
• Not suitable for cutting, maintenance, or anyone unwilling to commit to aggressive eating
• No direct hamstring or glute isolation — the program assumes Deadlift and Squat volume is sufficient for posterior chain development

Program Structure

• Split: Full body with emphasis rotation — Squat + Overhead Press on Monday and Friday, Deadlift + Bench Press on Wednesday
• Periodization: Two 3-week waves with a Training Max increase between them. Within each wave, intensity follows a medium/light/heavy pattern (not the standard 5/3/1 ascending order)
• Schedule: Fixed Mon/Wed/Fri. Conditioning is mandatory on Tue/Thu/Sat (prowler sprints, weighted vest walks, or stationary bike)
• Unique features: Monday Overhead Press includes an AMRAP back-off set. Friday has a 20-rep widowmaker Squat and high-volume Overhead Press (10-15 sets of 5)

Exercise Selection & Rationale

Main lifts rotate across three training days:

• Monday (Squat + Overhead Press): Squat gets the heaviest treatment with 5x5 at the top percentage. Overhead Press includes an AMRAP back-off set at the lowest percentage for volume and auto-regulation.
• Wednesday (Deadlift + Bench Press): Deadlift uses fewer top sets (3x5 vs 5x5) because of its higher systemic fatigue. Bench Press gets the full 5x5 treatment.
• Friday (Squat + Overhead Press volume): Squat ramps to a single heavy set then drops to a 20-rep widowmaker — the defining feature of the program. Overhead Press gets high-set volume (10-15 sets of 5) at moderate weight.

Accessories are chosen for high-rep accumulation:

• Chin Up (Monday: 100 bodyweight reps; Friday: 5x5 weighted): Vertical pulling to balance pressing volume and build back width.
• Chest Dip (Monday: 150 reps): Upper body pressing volume that complements Bench Press and Overhead Press.
• Face Pull (Monday and Friday: 100 reps each): Rear delt and upper back health to counterbalance heavy pressing. Band pull-aparts can substitute.
• Bent Over One Arm Row (Wednesday: 5x10-20): Heavy horizontal pulling for back thickness.
• Bicep Curl (Wednesday: 100 reps): Direct arm work — the only isolation exercise in the program.
• Shrug (Friday: 100 reps): Trap development to support heavy barbell work.

All accessories can be swapped for similar movements — e.g., Pull Up for Chin Up, Triceps Dip for Chest Dip, Bent Over Row for Bent Over One Arm Row.

Set & Rep Scheme

Main lifts follow the 5/3/1 wave pattern, but all working sets stay at 5 reps (no 3s or 1s weeks). Percentages are based on a Training Max (TM) of 85% of 1RM. In this Liftosaur implementation, percentages are expressed as % of 1RM directly (pre-converted from TM):

• Weeks 1 and 4 (Medium): Warm-up sets at 60% and 68%, top sets at 76% of 1RM
• Weeks 2 and 5 (Light): Warm-up sets at 55% and 64%, top sets at 72% of 1RM
• Weeks 3 and 6 (Heavy): Warm-up sets at 64% and 72%, top sets at 80% of 1RM

Squat gets the most volume: 7 working sets on Monday (1x5, 1x5, 5x5 at top weight) and 3 ramp-up sets + 1x20 widowmaker on Friday. Deadlift gets fewer top sets (3x5 instead of 5x5) due to systemic fatigue. Bench Press mirrors Squat's 5x5 structure. Overhead Press has 3 working sets plus an AMRAP back-off set on Monday, and 10-15 sets of 5 on Friday.

The AMRAP set on Monday Overhead Press provides auto-regulation — don't push to absolute failure, stop with 1-2 reps in reserve. Wendler says not to chase rep PRs in the first 3-week wave; save that for the second wave.

Widowmaker Squat (Friday): 1 set of 20 reps, climbing from ~40% to 60% of 1RM over the 6 weeks. Do not re-rack the bar during these 20 reps — rest-pause at the top position (standing with the bar on your back) is acceptable.

Accessories: 100+ total reps broken into as many sets as needed. For bodyweight Chin Ups and Chest Dips, this might be 10x10, 5x20, or any combination.

Progressive Overload

The program uses two 3-week waves with a Training Max increase between them:

• Weeks 1-3: First wave at your starting weights
• After Week 3: 1RM increases by +5 lbs for Overhead Press and Bench Press, +10 lbs for Squat and Deadlift
• Weeks 4-6: Second wave at the new weights — same percentage pattern but applied to the higher 1RM

There is no failure-based deload. The program is designed to be completed as written over exactly 6 weeks, with the weights being manageable if your Training Max is set correctly.

If you can't complete the prescribed sets: Your TM is too high. Wendler specifically recommends TM at 85% of true 1RM for this program (lower than the 90% used in other 5/3/1 templates). Start conservatively — finishing all 6 weeks matters more than impressing yourself in week 1.

How Long to Run It / What Next

Run Building the Monolith for exactly 6 weeks. Do NOT repeat it immediately. Take a deload week, then transition to a less demanding template.

Signs it's working: Bodyweight is climbing, clothes fit tighter in shoulders and thighs, widowmaker squat weight is increasing each week.

What next: 5/3/1 Boring But Big (similar philosophy but sustainable long-term), 5/3/1 First Set Last (lower volume for recovery), or any standard 5/3/1 template. Wendler specifically warns against jumping into another extreme block immediately.

Equipment Needed

Barbell, squat rack, bench, weight plates, a pull-up/chin-up bar, and dumbbells for rows and curls. A cable machine for Face Pulls is ideal but not required.

Home gym substitutions:

• Face Pull → Reverse Fly with dumbbells, or band pull-aparts
• Bent Over One Arm Row → Bent Over Row with barbell
• Bicep Curl → Bicep Curl, Barbell with straight bar or EZ bar
• Shrug → Shrug, Barbell
• Chest Dip → Push Up with a weight vest if dip station unavailable
• Chin Up (weighted on Friday) → Chin Up with a dumbbell between feet or a dip belt

Rest Times

• Main compound sets (Squat 5x5, Bench Press 5x5, Deadlift 3x5): 3-5 minutes between working sets
• Friday Overhead Press (10-15 sets of 5): 60-90 seconds — keep these moving at the prescribed moderate weights
• Widowmaker Squat: Rest as long as needed before starting. Perform it last on Friday.
• 100-rep accessories (Chin Up, Chest Dip, Face Pull, Bicep Curl, Shrug): 60-90 seconds between sets. Can be supersetted (e.g., Face Pulls between Chin Up sets) to save time. Do NOT superset main compound lifts.

How to Pick Starting Weights

1. For each main lift (Squat, Bench Press, Deadlift, Overhead Press), estimate or test your 1 Rep Max (1RM). This Liftosaur implementation uses 1RM directly — all working percentages are pre-converted from Wendler's TM-based percentages (assuming TM = 85% of 1RM).
2. Set your 1RM in the app and all weights calculate automatically.

If you don't know your 1RM: Work up to a weight you can do for 3-5 clean reps. Use Brzycki's formula: 1RM = weight / (1.0278 - 0.0278 × reps). Or use the Liftosaur 1RM calculator.

Common mistake: Setting your 1RM too high. Wendler uses a lower TM (85% vs the usual 90%) for this program specifically because the volume is so high. If your Week 3 heavy sets at 80% of 1RM feel like absolute grinders, your 1RM is inflated — lower it by 5-10%.

Accessories: Chin Ups and Chest Dips are bodyweight. For Face Pulls, Bicep Curls, Shrugs, and Bent Over One Arm Rows, start with a moderate weight that lets you accumulate the total reps without individual sets going to failure.

Common Modifications

• Reduced dip volume: If 150 dips is too much for your shoulders, start at 50-75 and add 10-15 per week. Push Ups can substitute if dips cause joint pain.
• Safety squat bar for widowmakers: Wendler suggests using an SSB for the 20-rep set if available — reduces upper back fatigue and lets you focus on leg drive.
• Conditioning: Wendler mandates 3-4 conditioning sessions per week on off-days. Prowler sprints (10 x 40 yards), weighted vest walks (2 miles at ~80 lbs), and stationary bike (10 miles at moderate pace). Hill sprints are NOT recommended — too taxing alongside this training volume.
• Older lifters: Wendler recommends reducing widowmaker percentages by 5-10% and being more conservative with the TM.
• No joker sets: Wendler explicitly forbids joker sets in this program — a test subject tried them on Deadlift and nearly had to abandon the program.
• No added exercises: Run the program as written. Do not combine with Olympic lifts or add extra work beyond the prescribed conditioning.

FAQ

Is 5/3/1 Building the Monolith good for beginners?

No, Building the Monolith is an intermediate to advanced program requiring 2+ years of training experience. You need to be able to accumulate 50+ chin-ups and 50+ dips in a single session before starting. Try 5/3/1 for Beginners or Boring But Big first.

How many days a week is Building the Monolith?

It's a 3-day lifting program (Monday/Wednesday/Friday) with mandatory conditioning on 3-4 off-days. Sessions run 90-120+ minutes due to the extreme accessory volume — 100+ reps each of chin-ups, dips, face pulls, and other exercises.

How long is the Building the Monolith program?

It's exactly 6 weeks — two 3-week waves with a Training Max increase between them. Do not repeat it immediately. Take a deload week afterward, then transition to a less demanding 5/3/1 template.

What are the diet requirements for Building the Monolith?

Wendler mandates eating 1.5 lbs of ground beef and 12 whole eggs daily, which works out to roughly 5,000+ calories. The program punishes you if you don't eat enough — the extreme volume and 20-rep squat sets are only recoverable with aggressive caloric surplus.

What is the widowmaker squat set in Building the Monolith?

Every Friday includes one set of 20 reps of squats, climbing from about 40% to 60% of 1RM over the 6 weeks. You don't re-rack the bar during the 20 reps — rest-pause at the top position is acceptable. It's the defining and most brutal feature of the program.

What should I do after Building the Monolith?

Transition to 5/3/1 Boring But Big (similar philosophy but sustainable long-term), 5/3/1 First Set Last (lower volume for recovery), or any standard 5/3/1 template. Wendler specifically warns against jumping into another extreme block immediately.
