Overview
Weighing 36.4 pounds, the K K-021DZ-K is a carbon steel weight bench finished in black, with a listed length of 31 inches and a footprint of 31.8 by 14 inches. It is built as a stable base for dumbbell or bodyweight work.
A carbon steel frame at just over 36 pounds sits on the lighter end for a weight bench, which makes it easier to move around a room but is worth weighing against how much load you plan to put on it during pressing or stepped exercises, since the listing does not state a maximum user weight. The 13.5 inch height and 14 inch width describe a compact bench rather than a wide, adjustable one.
- Material: carbon steel
- Frame weight: 36.4 pounds
- Footprint: 31.8"D x 14"W x 13.5"H
- Color: black
Who it's for
Works for home gym setups with limited space, where a compact flat bench is enough for dumbbell presses, rows and step exercises. Buyers who need incline or decline adjustment, or a published weight capacity, won't find that confirmed in this listing.
Strengths and trade-offs
Drawn from this product's published specifications.
- Lightweight steel frame is easy to move
- Compact footprint suits smaller rooms
- No stated weight capacity
- No mention of incline or adjustability
Performance notes
Carbon steel is the standard frame material for this bench class, chosen for rigidity under load. At 36.4 pounds the frame is light enough to reposition without help, and its 31.8 by 14 inch footprint fits into a smaller training space than a full-size adjustable bench would need.
