ECHO is built around one idea: every muscle gets trained in a block — two exercises, same muscle, back to back. A heavy compound movement followed by an isolation. Then four structured sets for each: a prep set to prime the pattern, a heavy potentiation set to activate your nervous system, and two back-off sets where the real work happens. It's not complicated. But it's specific — and that specificity is what makes it work. Best for anyone who wants a clear system, measurable progress, and a program that compounds over 8 weeks.

ANCHOR is built around practice. You choose one main lift per movement — then you do it twice: once heavy to build strength, once lighter to refine it. Four modules, one lift each, repeated every week. No pairing, no racing the clock. Just deliberate sets, full rest, and measurable progress over 6 weeks.

DENSITY is built around time, not reps. Each block gives you a fixed window — you alternate between two movements, push the pace, and let the clock keep score. No guessing on sets. No waiting. Just work density that builds conditioning and strength at the same time. Best for anyone who wants structure with urgency, measurable output each session, and a program that gets harder as you get better.
