TRAINING + NUTRITION · ONE ENGINE
Your plan isn't improvised. It's forged.
Forjium is the AI coach that does what a real coach does: periodizes your macrocycle, progresses your loads, schedules your deloads and aligns your diet with your training. All you do is execute.

WHAT THEY'RE SELLING YOU
Your app hands you a Monday-to-Sunday table. And calls it artificial intelligence.
We tested them. Under the hood, most are the same thing: a static template with a chat layer on top.
Random workouts dressed up as AI.
Exercises rotating weekly for no reason. Rotating without criteria kills the one non-negotiable: progressive overload.
Eleven sliders so YOU do the work.
If you're configuring volume, frequency and intensity by hand… you're the coach, not the app.
Training and diet that never talk.
Two separate agents: one raises your volume while the other cuts your calories. No real coach would ever do that.
A table doesn't react. An engine does.
WHAT'S UNDERNEATH
A real macrocycle. Not one week on repeat.
Weeks 1-4 · Accumulation.
The engine starts conservative and builds volume. 10-20 sets/muscle/week, every muscle ≥2×/week. Start low, build up — that's what the evidence says.
Week 4 · Deload.
No app schedules your rest. Forjium does: volume ×0.6 · intensity ×0.85. A deload isn't a lost week. It's what lets you keep climbing.
Weeks 5-8 · Intensification.
Loads go up because your logs justify it. Progression is computed from what YOU actually lifted, not from a made-up percentage.
Week 20 · Peak.
You finish the cycle with a plan that reacted to every session you logged. That's what a coach does. That's Forjium.
Exercises stay stable within each block, variation happens between blocks. The way real periodization works.
Training, diet and your real life. Decided together.
Your sport counts.
Padel on Wednesdays? Football on Sunday? The engine knows cardio-strength interference and repositions your volume so neither eats the other.
Macros that follow your cycle.
2,430 kcal isn't a fixed number: it rises in surplus, drops on deload, protects your protein always. Your diet obeys the same plan as your training.
Time Capsule.
Every set you log builds your history: PRs, loads per exercise, weekly adherence. A year from now, you'll want to see this.

Bench press · 4×8 · RIR 2 · rest 180 s. You know exactly what to do the moment you walk into the gym.

Every engine decision has a citation behind it.
We're not asking for faith. The engine is built on published evidence, and every plan explains its why.
-
Frequency ≥2×/week per muscle
— maximizes hypertrophy at equal volume (Schoenfeld et al., meta-analysis).
-
10-20 sets/muscle/week, close to failure
— the best-return range; diminishing returns above it (Schoenfeld 2017; recent meta-regressions).
-
Overhead triceps extension
— ~40% more long-head growth than pushdowns (Maeo 2023). That's why it's in your plan.
-
Progressive overload with stable exercises
— rotating exercises weekly hurts; systematic variation belongs between blocks (Kassiano et al.).
When Forjium changes your plan, it tells you why. Method transparency, not sweet talk.
Built for people who already train seriously.
It's for you if:
- you've trained 2-5 years
- you know what RIR means
- you're done progressing blind
- you want someone (or something) to think the plan through for you, with criteria
It's not for you if:
- you want 30-day challenges
- you want guided video classes
- you've never set foot in a gym (yet — come back in a few months)
Telling you who it's NOT for is also what a real coach would do.
FAQ
What makes Forjium different from Fitbod, Juggernaut, or any "AI coach"?
The engine. Forjium generates a full macrocycle with phases, progression computed from your actual logs, and scheduled deloads — and nutrition is decided in the same brain as training. It's not a weekly template with a chat.
Does the AI make up exercises or weights?
No. Program structure is fixed by a deterministic, evidence-based engine; the AI personalizes within those limits and only with exercises from our library. The AI never improvises your structure.
Do I need a full gym?
Gym or home with dumbbells. The engine filters every exercise by your actual equipment.
What about my sport (padel, football, running…)?
Declare it in onboarding and the engine manages the interference: it repositions volume to protect your legs before match day — or your match before leg day. You set the priority.
