The sled full hack squat is a lower-body strength exercise performed on a hack squat sled machine, taking the thighs through a full range of motion with your back supported against the angled pad. It targets the thigh muscles through a deep squat pattern, making it a reliable option for building leg strength and muscle when full depth is the training goal.
Sled Full Hack Squat: So führst du sie aus
- 1Step into the hack squat sled machine and position your back and shoulders flat against the angled pad, with your feet shoulder-width apart on the platform and toes angled slightly outward.
- 2Place your shoulders under the shoulder pads and grip the side handles to anchor your upper body.
- 3Disengage the safety handles and hold the sled with your legs extended, stopping just short of full knee lockout.
- 4Brace your core and keep your lower back pressed firmly against the pad throughout the movement.
- 5Inhale and lower the sled under control by bending your knees, keeping your heels flat on the platform and your knees tracking in line with your toes.
- 6Continue the descent until your thighs travel past parallel to the platform, reaching full depth while your lower back remains in contact with the pad.
- 7Exhale and drive evenly through your full foot to press the sled back up, extending your knees and hips simultaneously.
- 8Stop just short of full knee lockout at the top to keep tension on the thigh muscles, then begin the next rep.
- 9After completing all reps, engage the safety handles fully before stepping out of the machine.
Technik-Tipps
- Keep your heels flat on the platform for the entire set — if they rise during the descent, move your feet slightly higher on the platform to compensate for ankle mobility limitations.
- Drive your knees outward in line with your toes throughout the press, especially out of the bottom position where the thigh muscles are under the most load.
- Control the descent over two to three seconds rather than letting the sled drop freely — a slower eccentric increases time under tension for the thigh muscles and reduces joint stress.
- At the bottom of each rep, pause briefly before pressing — this eliminates momentum from the stretch reflex and ensures the thigh muscles initiate the drive rather than a bounce off the stops.
- Match your foot position consistently from set to set so the movement pattern stays stable as fatigue accumulates.
Häufige Fehler
- Not reaching full depth despite the exercise calling for it — stopping short of parallel defeats the purpose of the full-range variation and reduces thigh muscle development in the lengthened position.
- Allowing the lower back to round off the pad at the bottom of the rep, which transfers compressive load to the lumbar spine — reduce range of motion or adjust foot placement until mobility improves.
- Letting the heels rise off the platform during the descent, which shifts load away from the thigh muscles and increases stress on the knees — keep the full foot flat throughout.
- Locking the knees out completely at the top of each rep, which shifts load from the thigh muscles to the joint and reduces total time under tension — stop just short of full extension.
- Using so much weight that the descent cannot be controlled, causing the sled to drop quickly and the knees to absorb the impact at the bottom — select a load that allows a slow, steady lowering phase.
Häufig gestellte Fragen
What muscles does the sled full hack squat work?
The sled full hack squat primarily targets the thigh muscles through a deep squat pattern. Because the back is supported and the feet are positioned in front of the body, the quadriceps region of the thigh takes on the majority of the workload throughout the full range of motion.
What is the difference between a full hack squat and a regular hack squat?
The full variation requires you to lower the sled until your thighs travel past parallel to the platform, reaching the deepest range of motion the machine allows while keeping your lower back against the pad. A standard hack squat typically stops at or near parallel. The full range increases demand on the thigh muscles in the lengthened position.
How should I position my feet on the platform?
Place your feet shoulder-width apart with toes angled slightly outward, roughly centered on the platform. A higher foot position reduces how far forward your knees travel and can make reaching full depth more comfortable if ankle mobility is limited.
Is the sled full hack squat safe for the knees?
It is safe when performed with proper form — heels flat, knees tracking over toes, lower back against the pad, and a controlled descent. Problems arise when the weight is too heavy to control, the heels rise, or the lower back rounds at the bottom. Start with a conservative load and build range of motion gradually.
How deep should I squat on the full hack squat?
The goal is to reach full depth, meaning your thighs travel past parallel to the platform. Go as deep as you can while keeping your heels flat and your lower back in contact with the pad. If the back rounds before you reach parallel, that is your current safe depth — work on it progressively.
