SQMIZE® POWER PACK LCS620-FB Leg Curl/Extension Station

SQMIZE® LCS620-FB – Leg Curler & Leg Extender.

Gym-quality equipment for home use. Plate-loaded. Compact. Precise. 

The LCS620-FB combines proven biomechanics with solid flange bearings at critical points—where conventional machines use simple bearings that wear out over time. The result is a range of motion that feels just like a gym—in your home gym as well as in professional training facilities. 

Flange bearings. The difference is in the details. 

The swivel arm of the LCS620-FB is equipped with solid flange bearings and high-strength bolts. This means: consistently precise movement guidance, no play, no fatigue—even after years of intensive use. In this price range, that’s not a given. 

Hamstring curls and leg extensions. Switch in seconds. 

The LCS620-FB is a dual station—leg curl and leg extension in one compact machine. The dial offers 28 starting and training positions for precise adjustment of the range of motion. No reconfiguration, no tools—just turn the dial and keep training. 

Prone Leg Curl. More than just a dual station. 

The rear pad of the LCS620-FB also enables the prone leg curl—the leg curl in a prone position. An exercise that trains the leg curl from a different angle and significantly expands the station’s range of exercises. Most compact dual stations do not offer this. 

Individually adjusted. For every athlete.

Six adjustment points ensure a perfect fit—regardless of height and body proportions. The contoured seat cushion is adjustable to three different heights. The backrest is adjustable to six different depths and seven different angles. The knee pads are adjustable to eight different positions, and the leg rollers to sixteen. Every adjustment fits perfectly—precisely, quickly, and without compromise. 

A build that lasts. 

4-sided welded frame, weight capacity up to 150 kg, robust construction. The slightly upward-sloping weight plate holder makes loading and unloading easier—compatible with Ø 30 mm and 50 mm plates. 

Note. 

Weight plates and weight collars are not included.

Sehr zufrieden

Einfacher Aufbau und schneller Versand.
Wir konnten nun das Gerät testen und sind sehr überzeugt.
Es ist perfekt fürs Homegym, man kann das Gerät schnell und einfach auf die gewünschte Größe und Funktion umstellen.
Das einzige was etwas stört ist, dass das Gerät etwas wackelig bei der Aufnahme der Gewichte ist.
Kann ich trotzdem weiterempfehlen.

Gute Alternative zu Gymgeräten

Ich habe das Gerät erst kurz im Gebrauch. Es funktioniert sehr gut. Der Aufbau war einfach. Mich interessiert wie andere auch das Maximalgewicht. Gibt es hier Erfahrungen bzw. kann der Hersteller dazu bitte Angaben machen. Danke

Our feedback: Anmerkung der Redaktion: Vielen Dank für die Bewertung. Für das LCS620 gilt eine Maximallast von 150 kg.

Gutes Preis-Leistungs-Verhältnis bei Studioqualität für das Homegym. Pünktlich geliefert, wie immer.
Macht genau das, was es soll. Langzeittest kann ich leider zu diesem Zeitpunkt noch nicht abgeben.
Lohnt sich definitiv mehr als ein Aufsatz für die Bank.

leichter Aufbau und solide Qualität

Mein Beinbeuger/Strecker ist heute angeliefert worden und ich habe mich sogleich an den Aufbau gemacht. Dieser ist mit der Anleitung absolut leicht verständlich und gelang ohne Probleme.
Der Beuger/Strecker läuft Butterweich und steht dabei Felsenfest :-)
Ich bin absolut begeistert von diesem Gerät und würde es glatt wieder kaufen.
