The base framework features 4 anti-slip rubber pads that ensure the unit is floor-friendly and stable. Its overall assembled weight (with water) of 117 lbs./53 kg further grounds and improves its stability.

The rowing machine is considerably large, but not as bulky as the Concept2 Rower. Its overall assembled dimensions are 83” long by 22” wide by 21” high. In other words, it’s going to need a workout area with perimeters of 7′ length by 1’9” width.

An additional extra clearance of 0.5′ at the front/rear, and 1′-2′ on each side of it will be necessary for safety and easy access purposes. Especially, if it’s going to be used in a congested area.

There are no predefined resistance levels because it’s infinite. It is determined by the aggressive level of your workout. The harder and faster you pull the handle the more challenging your workout gets, otherwise, the resistance becomes less.
