Strength programming

Cycles measured in days

Most platforms force you onto a seven-day Monday/Wednesday/Friday grid. Real programs often run on 5, 8, or 10-day cycles. Colossus is cycle-based by default. A training cycle has a length in days, and the calendar walks the cycle independently of weekdays. A coach can drop a deload at cycle 4, day 3 and it lands on whichever calendar day that resolves to.

Per-set prescription

Every set has its own target rep range, tempo, intensity percentage, RPE, and RIR. Mark a set as warm-up or AMRAP with one tap. Dropsets, rest-pause clusters, myo-rep, and EMOM are built into the prescription model, so coaches set them directly rather than leaving instructions in a notes field.

Periodization templates

Author a linear, DUP, block, or 5-3-1 template once and apply it to any program. Modifiers fan out per cycle automatically: intensity ramps, volume drops on deload weeks, and top-set RPE caps in the back half of a block.

Smart Builder, and why it gives you the same answer twice

Pick a split, an experience level, and the equipment your client actually has. Smart Builder drafts the whole program: every day, every slot, every set, with the exercises chosen from the catalogue on movement pattern and muscle group rather than on whatever a text generator happened to say that morning.

It runs on rules over exercise metadata, not a language model, and that is a deliberate choice rather than a limitation. Three things follow from it, and all three matter more than novelty. The same inputs produce the same program, so the preview you approve is the program that gets written, not a second draft that quietly differs. There is no per-generation cost, so drafting twenty programs costs exactly what drafting one does, and none of it is billed back to you as a usage fee. And nothing about your clients is sent to a third party to be processed.

Every draft is yours to edit before it commits. Smart Builder gets you to a full program in seconds; what you do to it after that is ordinary programming.

PR ledger and plateau detection

Seven distinct PR types are tracked per lift: heaviest single, heaviest 3-rep, heaviest 5-rep, heaviest 8-rep, best estimated 1RM, best single-set volume, and best single-day volume. e1RM trends carry confidence bands and account for bodyweight using system mass, so an unweighted pull-up still produces a real e1RM at the client's own weight. A weekly job flags plateaus per lift so coaches see them before the client asks.
