How ForgeFit works

Every workout in ForgeFit has three things: a type (lifting, cardio, calisthenics, mobility, sport), a duration, and an intensity rating from 1–10. That's the minimum.

For lifts, you also log individual sets — exercise, weight, reps. Sets feed into your strength tiers and personal records automatically. There's no need to manually mark a PR; ForgeFit detects it the moment you log a heavier set or a higher rep count at the same load.

Points are the universal score across every workout type. The formula is deliberately simple:

points = duration_minutes × intensity × type_multiplier

Type multipliers reward harder training styles:

• Powerlifting / heavy lifting — 2.0×
• Calisthenics — 1.8×
• Hypertrophy / general lifting — 1.5×
• Conditioning / HIIT — 1.4×
• Steady cardio — 1.0×
• Mobility / stretching — 0.6×

Points roll up daily, weekly, and all-time. They're how the leaderboard ranks consistency — not just one heavy day.

For barbell lifts (squat, bench, deadlift, OHP), ForgeFit calculates your estimated 1RM from each set using the Brzycki formula (capped at 12 reps to avoid endurance inflation), then divides by your bodyweight to get a strength ratio.

That ratio maps to a tier — Untrained, Novice, Intermediate, Advanced, Elite — using benchmarks from Strength Level. Men and women get separate scales because that's how strength science actually works.

Bodyweight movements (pull-ups, push-ups, dips, muscle-ups) use a hybrid model. We evaluate two paths and take the higher tier:

1. Reps path — for unweighted sets, your max reps in a set maps to a tier (e.g. 20 strict pull-ups = Elite for men, 10 = Elite for women).
2. Load path — for weighted sets, added load divided by bodyweight gives a ratio. Reps are capped at 5 in the calculation so a long set with light added weight doesn't outrank a true heavy single.

Whichever path puts you in the higher tier is what shows on your profile. A high-rep beast and a weighted-vest specialist can both reach Elite — the system respects both expressions of strength.

Badges come in five tiers — Bronze, Silver, Gold, Platinum, Legend — and unlock automatically when you hit the underlying milestone. Categories include lift PRs (e.g. Plate Loader for a 1×BW bench), volume milestones (1,000 reps logged), calisthenics achievements (Muscle-Up Master, Lever Lord), and consistency awards.

Streaks count consecutive days with at least one logged workout. Miss a day and the streak resets — no freezes, no premium "save my streak" upsell. The honest version is the only version.

The calorie calculator uses the Mifflin-St Jeor equation for BMR, then applies an activity multiplier and an optional surplus/deficit. It outputs a daily target plus a macro split (protein / carbs / fat) you can adjust.

The food log lets you search a database of common foods, log servings, and track how you're hitting your macros across the day. Nothing fancy — because tracking food shouldn't require a UX tutorial.
