Hack Squat

So führst du sie aus

1. 1Preparation and positioning. Adjust the platform, shoulder/back pads, safeties, and start depth before loading. Confirm the catches operate and keep hands away from moving rails.
2. 2Starting position. Place both feet securely on the platform, brace against the pad, extend the legs enough to release the safety, and keep knees aligned with feet.
3. 3Eccentric phase. Lower the carriage under control by bending the hips and knees while keeping the foot or feet fully supported and the pelvis/back in controlled contact.
4. 4Bottom position. Stop at the deepest reproducible, pain-free range before the pelvis rolls, heels lift, knees lose control, or the machine reaches an unsafe stop.
5. 5Concentric phase / lockout. Push through the platform and extend the hips and knees to the defined top without bouncing or forcefully locking the knees.
6. 6Breathing and bracing. Brace before lowering, maintain pressure through the hardest portion, and exhale/reset when stable. Re-engage the safety before relaxing.
7. 7Valid rep. A rep uses the same foot position and depth, keeps the carriage controlled, and contains no bounce, heel lift, abrupt knee collapse, or safety contact.

Häufige Fehler

• Unstable foot pressure

  Korrektur: Keep heel, base of the big toe, and base of the little toe connected throughout the rep.

• Uncontrolled knee drift

  Korrektur: Let the knee travel with the toes and reduce load or depth if that alignment cannot be controlled.

• Forcing a universal depth

  Korrektur: Use the deepest repeatable, pain-free depth that preserves foot and trunk control.

• Hips and chest separating

  Korrektur: Rise with pelvis and ribcage together rather than shooting the hips up first.

Sicherheit

• Current hip, knee, ankle, or tendon symptoms call for an individually tolerated range and load; pain is not a cue to force alignment or depth.
• Adjust the machine to the user, verify the selector pin/attachment and safety stops, and keep hands, clothing, and other people clear of the moving lever, cable, and stack.
• Heavy efforts and prolonged breath-holding can produce large acute blood-pressure responses; people with cardiovascular disease or uncontrolled hypertension need medically appropriate intensity and breathing guidance.

Progressionen & Alternativen

• RegressionHorizontal Leg Press— Reduce strength, balance, or coordination demand while rehearsing the key pattern before returning to Hack Squat.
• ProgressionPaused Hack Squat— Increase load, range, instability, or skill demand after Hack Squat is repeatable through the planned volume with reserve and no technique drift.
• AlternativeGoblet Squat— Train a similar primary pattern with a different stability, equipment, or joint-loading profile when Hack Squat is impractical or poorly tolerated.
