Juggernaut Method 2.0 (2026): Chad Wesley Smith's Wave System
Ten reps, eight reps, five reps, three reps — the Juggernaut Method moves you through monthly waves from volume to intensity, AMRAP the last set of every week, and resets each month heavier. Chad Wesley Smith built a program that undulates itself.

The Wave Structure
The Juggernaut Method runs four monthly phases, each named for its rep scheme: the 10s WAVE, the 8s WAVE, the 5s WAVE, the 3s WAVE. Within each wave, three weeks undulate — accumulation (high volume, moderate load), intensification (moderate volume, heavy load), and realization (heavy singles or the AMRAP test). Each wave ends with an AMRAP set that sets the next month's training max. Volume waves build size; intensity waves build strength — the program cycles through both every four months.
The Four Phases
| Wave | Rep target | Intensity | Goal | AMRAP effect |
|---|---|---|---|---|
| 10s Wave | Sets of 10 | 60-75% — accumulation | Hypertrophy + work capacity | Set your next 8s max |
| 8s Wave | Sets of 8 | 70-80% — still volume | Strength-size transition | Set your next 5s max |
| 5s Wave | Sets of 5 | 75-85% — intensification | Strength | Set your next 3s max |
| 3s Wave | Sets of 3 | 80-90% — near-max | Peak strength / PRs | Set next cycle max |
The Weekly Layout
- •4 days a week — one competition lift per day: squat, bench, deadlift, overhead press
- •Each day runs through the week's wave percentages, ending in the AMRAP or 3-5 working sets
- •Accessory work is programmed — Juggernaut prescribes movement-pattern accessories, not a choose-your-own list
- •Wave reset: the AMRAP at the end of each wave recalculates your training max for the next phase
Who Juggernaut Is For
- •Intermediate lifters who want undulating periodization — not a fixed weekly grind
- •Lifters who want size AND strength — the 10s/8s waves are built-in hypertrophy blocks
- •People who plateaued on linear programs — the monthly max resets keep progression alive
- •Home gym owners — 4 days, one lift, no exotic equipment
Classic Juggernaut Errors
- •Grinding the AMRAP to failure — the rep-out sets your next training max; a bad rep-out means a bad next month
- •Starting the training max too high — same trap as 5/3/1; inflate the max and the whole wave collapses
- •Skipping the deload week — the program builds it in; cutting it turns accumulation into overtraining
- •Treating all waves the same — the 10s wave is supposed to feel light; the 3s wave is supposed to feel hard
Wave After Wave, PR After PR
Four months of undulating volume and intensity — a bar that handles the 3s wave is the bar for the whole program.

Monthly undulation means the bar sees everything from sets of 10 to near-maxes — versatility matters.

Frequently Asked Questions
What is the Juggernaut Method?
Chad Wesley Smith's undulating program: four monthly waves (10s, 8s, 5s, 3s) with weekly accumulation/intensification, AMRAP sets at each wave's end to reset the next month's training max.
How does the AMRAP work in Juggernaut?
The last working set each week is rep-out — the number you hit recalculates your training max for the next wave. A big AMRAP means a bigger jump next month; a grind means a smaller one.
Is Juggernaut good for intermediates?
Yes — it is designed for post-linear lifters. The built-in hypertrophy waves make it more complete than pure strength programs, and the monthly resets handle stalls automatically.
Juggernaut vs 5/3/1?
Both are 4-day, one-lift programs. Juggernaut undulates rep ranges monthly (volume → intensity); 5/3/1 stays on 5/3/1 percentages with monthly +5lb bumps. Juggernaut has more built-in hypertrophy; 5/3/1 is simpler.
How long is a Juggernaut cycle?
A full cycle is ~4 months — one month per wave (10s, 8s, 5s, 3s). Then reset your training max from the last AMRAP and run it again.
