SQMIZE® ELITE CLUB SQ-M635 Curl Bench 

On a curl bench, the contact between the upper arm and the support surface determines the quality of the repetition. The SQMIZE® ELITE CLUB SQ-M635 ensures this contact: a 66 cm wide bench with 7.5 cm of padding, an 8-position adjustable seat, and a frame made of 50 x 100 mm profile.

The Curl Bench

The bench is 66 cm wide. Both elbows rest shoulder-width apart, and the direction of pull remains stable throughout the entire repetition.

With 7.5 cm of padding, the upper edge supports the weight of the upper body, which is transferred through the armpit during heavy sets. The incline slopes from 30 to 26 cm in height: the arm maintains contact throughout the extension, and the armpit is supported at the top.

Seat height adjustable in 8 steps from 50 to 66 cm

You can adjust the desk to match your upper arm length by changing the seat height. A 16 cm adjustment range across 8 positions results in increments of just over 2 cm—precise enough to find the right position even with a 10 cm difference in height, and adjustable in seconds during your workout.

The seat cushion is 34 cm deep and tapers from 32 cm to 10 cm in width. The narrow front gives your thighs room so you can slide close to the bench.

Two rest heights for the curl bar

The rests are positioned at 40 and 55 cm. The lower position holds the barbell for starting the set from the extended position, while the higher position is for resting the bar between sets, with your upper body remaining on the bench. Nylon covers the contact surfaces and keeps the bar’s knurling from scratching the rest.

There’s one measurement you should check before buying: The shelves are 85 cm apart, measured from the outer edge of the columns. Your curl bar needs at least 85 cm of usable interior space between the mounts.

Weight Capacity of the Curl Bar

The shelves can hold up to 300 kg. An SZ bar with weight plates weighs far less than that, and it is precisely this margin that keeps the mounts aligned for years, even when the bar is dropped rhythmically during sets.

Frame, Footprint, and Weight

The frame combines three profiles: 50 x 100 mm for the load-bearing elements, 75 x 75 mm for the structure, and 100 mm round tubing on the column. The 50 x 100 mm profile is oriented on its edge in the direction of the bending load when you pull forward over the bench.

The footprint measures 107 x 89 cm with a total height of 94 cm. The 89 cm width comes from the support columns and holds the bar in place on the machine.

With a net weight of 45 kg, the bench stands on its own. When performing pull-ups from the extended position, the force acts forward and upward, and the 45 kg on the 107 x 89 cm base area counteracts this. A second person is sufficient for moving the bench around the gym.

Tested according to EN ISO 20957, Class S

The SQ-M635 is certified to Class S under EN ISO 20957-1. Class S is the classification for training areas with regulated access and supervision: gyms, clubs, hotels, sports halls, schools, and rehabilitation facilities. The test loads and number of load cycles there are significantly higher than those for home use. The bench is therefore approved for supervised gym use.

Padding

The seat and bench are upholstered in grained synthetic leather. The foam has a density of 120 kg/m³ and retains its shape under repeated point loads. This is especially important on the curl bench: there, the upper body presses against the same edge with each set via the armpit, and the support surface maintains the angle at which the upper arm rests.
