Moment Arm
The perpendicular distance from the axis of rotation to the line of action of a force. Crucial for understanding leverage and resistance in lifting.
Bakit ito mahalaga:
A longer moment arm means more torque required, making a lift feel heavier. Optimizing moment arms improves efficiency and reduces injury risk.
Joint Stacking
Aligning joints (shoulder, hip, knee) vertically over the bar or line of force for maximum stability and force transfer.
Bakit ito mahalaga:
Efficient joint stacking minimizes energy leaks and allows you to lift heavier weights with less effort, preventing unnecessary strain.
RPE (Rate of Perceived Exertion)
A subjective scale (typically 1–10) used to measure the intensity of your effort during a set, helping to autoregulate training.
Bakit ito mahalaga:
RPE allows for flexible programming based on daily readiness, preventing overtraining and ensuring consistent, effective stimulus.
Bar Path
The trajectory of the barbell during a lift. Optimal bar path is often a straight vertical line over the midfoot.
Bakit ito mahalaga:
An efficient bar path minimizes horizontal displacement, reducing wasted energy and increasing the amount of weight that can be lifted.
Bracing
The act of creating intra-abdominal pressure by taking a deep breath and expanding your abdomen against your core muscles.
Bakit ito mahalaga:
Proper bracing stabilizes the spine and core, protecting against injury and allowing for more efficient force transfer during heavy lifts.
Progressive Overload
Gradually increasing the stress placed on the musculoskeletal system to stimulate adaptation and continuous improvement in strength or size.
Bakit ito mahalaga:
It's the fundamental principle of strength training. Without it, your body won't have a reason to get stronger or bigger.
Hook Grip
Isang grip kung saan ang hinlalaki ay nakadiin sa bar muna at ang mga daliri ay nakabalot sa hinlalaki, naka-lock sa lugar nito. Standard sa snatch at clean.
Bakit ito mahalaga:
Non-negotiable sa Olympic lifting. Pinipigilan ng hook na umikot ang bar palabas ng kamay sa pull — kung wala ito, mawawala ang peak velocities at mahuhuli ang elbows sa catch.
Triple Extension
Ang sabay-sabay na full extension ng ankles, knees, at hips sa tuktok ng pull. Ang pinakaimportanteng power moment sa snatch at clean.
Bakit ito mahalaga:
Halos lahat ng Olympic-lift miss ay galing sa incomplete o out-of-sequence triple extension. Sinusukat ng FormForge ang timing offset ng tatlong joints — ang "TES" reading.
TES (Triple Extension Speed)
Ang signature metric ng FormForge: angular velocity (deg/s) ng ankle + knee + hip extension sa second pull, peak-detected mula sa BlazePose landmark trajectories.
Bakit ito mahalaga:
May correlation ang TES sa vertical bar velocity sa snatch at clean. Pag-track ng TES sa mga sessions ay nagpapakita kung ang "explosive" intent mo ay talagang gumagawa ng speed — o pakiramdam lang na mabilis.
Catch Depth
Ang hip-crease height sa ilalim ng receive position sa snatch, clean, o overhead squat. Mas mababang catch = mas kaunting bar travel = mas mabigat na load posible.
Bakit ito mahalaga:
Ang catch depth ang pinakamurang free strength gain sa weightlifting: ang pag-develop ng mobility para ma-receive ng 5 cm na mas mababa ay pwedeng mag-resulta sa 5 kg na karagdagan sa bar nang walang extra force production.
Sinclair Score
Body-weight-adjusted total na ginagamit ng IWF para ikumpara ang lifters sa iba't-ibang weight classes. Kinakalkula mula sa total ng athlete (snatch + clean & jerk) at coefficient na naka-index sa current world records.
Bakit ito mahalaga:
Kapag hindi mo na mapalitan ang weight class, sinasabi ng Sinclair kung tumitibay ka talaga — independent sa bodyweight drift. Ito ang metric na nagde-decide ng "best lifter" awards sa karamihan ng meets.
Velocity-Based Training (VBT)
Programming base sa bar speed (Mean Propulsive Velocity, MPV) kaysa fixed %1RM. Pinapakita ng kamakailang meta-analyses na ka-match ng VBT ang PBT sa strength habang pinapabuti ang daily regulation.
Bakit ito mahalaga:
Nagbabago araw-araw ang tunay mong 1RM (tulog, stress, fueling). Sa VBT, hahayaan mong pumili ng load para sa araw na ito ang bar speed — kaya nananatiling mabigat ang heavy days at honest ang recovery days, nang walang coach sa silid.
