Built for Intermediate Lifters. Designed for Continuous Progress.
1-2 Years of Training | 4x Per Week | 12 Weeks

You've put in the work. You know the movements. Now it's time to train in a way that matches where you actually are.
The Undulated program cycles between two distinct training stimuli — muscle building phases and strength phases — alternating every 3 weeks throughout the full 12 weeks. This back and forth is what separates intermediate programming from beginner programming. Your body has already adapted to the basics. Now it needs variety in the right doses at the right times to keep progressing.
This isn't random variety — it's strategic variation. Each muscle building phase sets up the strength phase that follows. Each strength phase makes the next muscle building phase more productive. The cycle compounds over 12 weeks into real, measurable results.
The exercise selection also shifts between phases — giving your joints and muscles fresh stimulus while keeping the fundamental movement patterns consistent. You'll recognize the movements. The demands will change.
If Linear was learning the language — Undulated is having your first real conversation.
5 Benefits for the Undulated Program
Alternating between muscle building and strength phases every 3 weeks keeps your body constantly adapting — no plateaus, no wasted weeks, no guesswork.
Strategic Phase Cycling
More Muscle. More Strength. At the Same Time.
The Undulated structure doesn't force you to choose between size and strength. Each phase feeds the next — muscle built during accumulation becomes strength during intensification.
Exercise selection shifts between phases — giving your joints and muscles fresh stimulus while keeping the fundamental movement patterns consistent. Variety that actually means something.
Exercise Variation With Purpose
Every phase is designed to build on the last. Week by week, phase by phase, the program gets harder in exactly the right ways — not randomly, not arbitrarily.
Progressive Overload Built In
Completing the Undulated program doesn't just get you stronger for 12 weeks — it prepares your nervous system and training habits for the more advanced demands of the Undulated Integrated program.

Frequently Asked Questions
-
Linear keeps the same exercises for 6 weeks at a time to build motor patterns. Undulated alternates between muscle building and strength phases every 3 weeks with different exercise selections. It's more dynamic, more demanding, and designed for lifters who already have their movement foundations locked in.
-
If you've been following a structured program consistently for at least a year and feel confident in your fundamental movements — squat, press, hinge, pull — you're ready for Undulated. If you're unsure go one level down and start with Linear. The program that challenges you appropriately will always outperform the one that overwhelms you.
-
You have two paths. Repeat the Undulated program — your strength numbers will be higher and the same program will produce new adaptations. Or step up to the Undulated Integrated program if you have 2 or more years of training under your belt and want a more advanced stimulus. Level 2 and Level 3 Undulated programs are also coming soon with progressive exercise variations built on your existing foundation.
