Performance improves fastest when movement, mind, and environment are intentionally designed — not left to chance. Our promise: no grind culture, just physics-informed progress. Boring, repeatable strength that fits around your real life.
Work. Grad school. Heavy lifting. Family. Your time is the budget, not your motivation. Tim built FormForge while finishing his PhD, defending his thesis, and prepping for a sanctioned meet — so the system you train inside is the same one he tests on himself.
Joint-first exercise selection. Athlete-safe language. Trends over scores. "If the week feels like too much, your first 'win' is trimming, not quitting — this plan is meant to bend with your life."
In FormForge, "forge" means to actively shape and synthesize science into human performance. We transform Physics, Physiology, and Psychology into Fab Form, Fit, and Flow — through deliberate design, evidence-based feedback, and human-centered coaching.
Bar path, joint sequencing, force timing. Engineered for power and durability. Larger moment arms require more force to move the same weight — so we measure them.
Body × task × context. Objectively measured, coach-interpreted. Different lifters need different geometry — your hips, your levers, your fatigue floor.
Mental rhythm, motivation, confidence. Designed through pacing, feedback loops, and habit formation. Not accidental. Forged.
To forge is to actively shape through intention. We synthesize three disciplines (Physics, Physiology, Psychology) into three outcomes (Fab Form, Fit, Flow). Not gimmicks. Not generic. Engineered.
Both tracks are joint-respectful, science-backed, and built for busy brains. Your assessment tells Tim which to start with — and you can layer the second once your base + schedule feel steady.
Joint-first exercise selection. Built around lever-friendly variations. Beginner-safe, return-from-break ready, joint-tweak respectful.
For those with a base and a bit more flexibility. Snatch + clean & jerk on purpose, layered on top of your strength engine. Patient enough to practice with a PVC pipe? You're our person.
Most tracker apps log reps. FormForge measures movement — joint by joint, frame by frame — then maps it to peer-reviewed biomechanics so you train the right thing next session.
Real-time pose overlay (33 landmarks, 3D) on your phone or laptop camera. Bar-path heat-line, joint-angle readouts, side-symmetry delta — no install.
Color-track your barbell through any uploaded video. Get vertical-displacement, peak velocity, and Cuban-hook deviation — overlay against a reference rep.
Drag in OpenCap CSVs from any iPhone-pair capture. Auto-segment Snatch / Clean / Jerk phases. Compute Triple-Extension Speed (TES), catch depth, dip-drive, and L-R symmetry.
Stick-figure skeleton rendered in Three.js with phase markers, ghost overlay (Rep B), and scrubbable timeline. Compare your snatch to your best — or to an elite reference.
Mean propulsive velocity (MPV) → estimated %1RM and load-velocity profile. Camera-only velocity proxy when you don’t have a Vitruve / Enode.
Workout log with auto-form scoring per set, RPE, e1RM, weekly volume, and PR feed. Lives on your device — exports to CSV.
Roster, video review queue, athlete-safe note templates, status updater, and shareable annotated clips. White-label-ready for federations.
Athletes look up Job IDs, see queue status, and receive results via email/PWA push when their coach hits “DONE.” Powered by Apps Script + URLFAM PWA.
Every metric in FormForge maps to validated research. We cite OpenCap (Stanford NMBL, PLOS Comp Bio 2023), the BlazePose 33-landmark topology (Google Research), and recent VBT meta-analyses on velocity-load profiling.
“I got more from one upload than three months of generic programming. The phase markers exposed exactly where my dip-drive was leaking power.”
“The 3D ghost overlay let my athletes see what ‘good’ looks like. We replaced 40% of cueing with the player.”
“Finally a tool built by someone who actually understands physics. The asymmetry index caught my hip imbalance before my PT did.”
33 AI-composed instrumental tracks built for weightlifting content — so your training videos never get auto-muted on YouTube or IG. Free to stream, ₱99/mo for the creator license.

FormForge stands on three peer-reviewed pillars: markerless 3D motion capture, browser-grade pose estimation, and validated velocity-based training. Here is what we use, why, and where to read the source.
PhD Student · Founder, FormForge
Applied Physics & Materials Science PhD Student. UPWC Gold Medalist. Peer-reviewed researcher, published Taylor & Francis 2026. Building FormForge to bring physics-grade coaching to every lifter.
🔗 Tim's full profileTim is a PhD Student in Applied Physics & Materials Science and Engineering. After watching too many lifters injure themselves chasing kilos with bad mechanics, he built FormForge so any athlete with a phone could see their lift the way a scientist sees it: as force, leverage, and geometry over time. No gimmicks. No medical claims. Just objective data, delivered with athlete-safe language.
Open-source markerless motion capture using two iPhones. Validated lower-extremity kinematics with RMSE 2.0–10.2° vs. marker-based gold standard.

Mean magnitude of d(hip + knee + ankle)/dt during the power phase. Higher TES correlates with elite snatch / clean output. Reference: heavy snatch bar speed 1.52–1.67 m/s.
Maximum knee flexion within the catch window. Tracks both mobility and confidence under load. We compare each rep to your own moving average.
Dip depth (deg) and drive speed (rad/s) computed from knee-angle derivative. Athlete-safe flags such as “TES low” instead of “bad rep.”
Mean absolute left-right difference for each joint across the rep. Used to flag asymmetric loading patterns before they become problems — never as a medical diagnosis.

The perpendicular distance from the axis of rotation to the line of action of a force. Crucial for understanding leverage and resistance in lifting.
Why it matters:
A longer moment arm means more torque required, making a lift feel heavier. Optimizing moment arms improves efficiency and reduces injury risk.
Aligning joints (shoulder, hip, knee) vertically over the bar or line of force for maximum stability and force transfer.
Why it matters:
Efficient joint stacking minimizes energy leaks and allows you to lift heavier weights with less effort, preventing unnecessary strain.
A subjective scale (typically 1–10) used to measure the intensity of your effort during a set, helping to autoregulate training.
Why it matters:
RPE allows for flexible programming based on daily readiness, preventing overtraining and ensuring consistent, effective stimulus.
The trajectory of the barbell during a lift. Optimal bar path is often a straight vertical line over the midfoot.
Why it matters:
An efficient bar path minimizes horizontal displacement, reducing wasted energy and increasing the amount of weight that can be lifted.
The act of creating intra-abdominal pressure by taking a deep breath and expanding your abdomen against your core muscles.
Why it matters:
Proper bracing stabilizes the spine and core, protecting against injury and allowing for more efficient force transfer during heavy lifts.
Gradually increasing the stress placed on the musculoskeletal system to stimulate adaptation and continuous improvement in strength or size.
Why it matters:
It's the fundamental principle of strength training. Without it, your body won't have a reason to get stronger or bigger.
A grip where the thumb is pressed against the bar first and the fingers wrap over the thumb, locking it in place. Standard for the snatch and clean.
Why it matters:
Non-negotiable for Olympic lifting. The hook prevents the bar from spinning out of the hand during the pull — without it, peak velocities are lost and elbows turn over late on the catch.
The simultaneous full extension of the ankles, knees, and hips at the top of the pull. The single most important power moment in the snatch and clean.
Why it matters:
Almost every Olympic-lift miss traces back to incomplete or out-of-sequence triple extension. FormForge measures the timing offset between the three joints — the "TES" reading.
FormForge's signature metric: the angular velocity (deg/s) of ankle + knee + hip extension during the second pull, peak-detected from BlazePose landmark trajectories.
Why it matters:
TES correlates with vertical bar velocity on the snatch and clean. Tracking TES across sessions shows whether your "explosive" intent is actually producing speed — or just feeling fast.
The hip-crease height at the bottom of the receive position in the snatch, clean, or overhead squat. Lower catch = less bar travel required = heavier loads possible.
Why it matters:
Catch depth is the cheapest free strength gain in weightlifting: developing the mobility to receive 5 cm lower can mean 5 kg more on the bar with no extra force production.
The mean absolute left-right difference for a given joint angle across the rep, expressed in degrees. Every athlete has some asymmetry — the question is whether it's stable, drifting, or flaring.
Why it matters:
This is surveillance, not diagnosis. A drifting delta doesn't mean an injury exists — it means the next two sessions deserve a closer look. Real pain always belongs with a qualified medical professional.
A body-weight-adjusted total used by the IWF to compare lifters across weight classes. Calculated from the athlete's total (snatch + clean & jerk) and a coefficient indexed to current world records.
Why it matters:
When you can't change weight classes, Sinclair tells you whether you're actually getting better — independent of bodyweight drift. It's the metric that decides "best lifter" awards at most meets.
Programming based on bar speed (Mean Propulsive Velocity, MPV) instead of fixed %1RM. Recent meta-analyses show VBT matches PBT for strength while improving daily regulation.
Why it matters:
Your real 1RM changes daily (sleep, stress, fueling). VBT lets the bar speed pick today's load — so heavy days stay heavy and recovery days stay honest, without a coach needing to be in the room.
The Philippine national school athletics meet. 2026 is the first year weightlifting was included as a regular sport, opening a new pipeline for PH-grown WL talent — and a new set of coaching needs at the school level.
Why it matters:
For coaches new to WL, this means accelerated capacity-building. For parents, structured pathways from school to club to the elite ranks. For athletes, meet experience earlier in their development. FormForge offers free tools and a Coach Pro tier built specifically for Palaro-bound school programs.
Click the bar at the start of your pull, then again at lockout, to measure vertical displacement and average velocity. Works on any bar, any background.
Calibrate real-world distance by clicking two reference points — plate diameter, floor-to-lockout, or bench bar height — so every metric after that is accurate.
Setup, First Pull, Extension, Catch, Stand — every snatch breaks down into these five phases. Knowing them helps you spot exactly where a lift breaks down.
Setup, First Pull, Extension, Rack, Dip, Jerk Lockout — the clean gets the bar to your shoulders, the jerk sends it overhead. Six stages, two separate lifts.
The explosive phase right after the transition (knee scoop), where the lifter drives hard to accelerate the bar upward. This is the phase where Triple Extension actually happens.
A physicist's field guide to auditing your snatch, clean & jerk, squat or deadlift — using nothing more than a phone camera and three peer-reviewed metrics.
Hi — I'm Tim. After watching too many talented lifters plateau or get hurt chasing PRs with leaky mechanics, I built FormForge so any athlete with a phone could see their lift the way a scientist sees it. This guide hands you my shortlist: the three numbers I check first on every video review.
None of this is medical advice. These are objective signals that let you make smarter decisions about the next session — not the next surgery.
How fast your hip + knee + ankle straighten during the power phase. If your bar barely floats, this number is too low.
How deep you're willing — and able — to drop into the catch. The cure isn't more reps; it's mobility plus rehearsed depth.
How much your left and right sides disagree, frame by frame. Lower is better — never a diagnosis, always a flag.
I personally voice-back the top three fixes for ten lifters every week. It's free.
Limited to 10 audits per week. Drop your email + a video link (YouTube / Drive / Dropbox) and you'll hear back within 72 hours with the top 3 things to fix on your next session.
If you have a question we missed, hit "Get Free Form Audit" in the nav — Tim will answer.
