The Juggernaut Method: how progression works

Chad Wesley Smith created the Juggernaut Method as a long-term strength program built around the squat, bench press, deadlift, and military press (overhead press).

Each lift moves through four waves: 10s, 8s, 5s, and 3s. A wave starts with higher-volume work, builds to a realization week with an AMRAP set, then finishes with a deload. The later waves use fewer reps and heavier percentages.

Your reps in the realization set determine how your Working Max changes for the next wave. This ties the increase to your performance across the full wave instead of one workout.

The method becomes useful after beginner progression has run its course. Intermediate and advanced lifters often need more training and recovery between meaningful load increases. The Juggernaut Method provides that time through planned blocks instead of asking you to add weight every session.

The 10s and 8s waves provide high-volume practice with manageable weights. That work can build muscle, improve work capacity, and give you more chances to refine your technique. The 5s and 3s waves then shift the same lifts toward heavier strength work.

The method also suits lifters who want their progress to reflect performance. The realization set ties the next WM increase to your extra reps. A strong result earns a larger increase, while hitting the wave target keeps the WM steady.

You need a stable set of main lifts and enough time to complete the cycle. Running the 10s, 8s, 5s, and 3s waves takes 16 weeks when each wave includes its deload. The squat, bench press, deadlift, and overhead press fit this structure because you can practise them for months and measure progress against the same movements.

Chad Wesley Smith calls this number a Working Max, shortened here to WM. It gives the percentages a conservative starting point below your true maximum.

Your WM is a conservative reference for calculating training weights. A common starting point is 90% of a recent true or estimated 1RM. Starting below your best lift gives you room to complete the planned volume and improve across several waves.

If your recent squat 1RM is 160 kg, a 90% WM is 144 kg. A set prescribed at 70% uses 100.8 kg before you round it to a weight you can load.

The number in each wave tells you its main rep target. The 10s wave starts with lighter, higher-rep work. The 8s, 5s, and 3s waves raise the percentage as the rep target drops.

Each wave runs through accumulation, intensification, realization, and deload phases. Keep those weeks in order because each one prepares you for the next part of the wave.

Suppose your squat WM is 140 kg and you have reached the realization week of the 8s wave. The realization set uses 80% of your WM, which gives you 112 kg before rounding.

You complete 11 reps. The wave target is 8, so you performed 3 extra reps. Multiply those extra reps by your chosen increment, then add the result to your current WM.
