Overview
At 18 pounds, the Cap FM-703B is a lighter flat bench than most, built from an alloy steel frame with a vinyl pad. It measures roughly 46.5 inches long, 18 inches wide, and 19 inches tall, finished in black.
At 18 pounds this is noticeably lighter than heavier-gauge flat benches, which makes it easier to move but likely less planted under heavy loading. Its low 19 inch height keeps the pad close to the floor, a detail that matters for exercises like step-ups or seated presses where bench height changes the movement.
- Alloy steel frame with vinyl pad
- 18 pound unit weight
- Roughly 46.5 by 18 by 19 inches
- Black finish
Who it's for
Fits lifters who want a lightweight, easy to move flat bench for dumbbell work in a home setup. Less suited to anyone loading very heavy weight who wants a bench with more mass underfoot.
Pros and cons
- Lightweight at 18 pounds, easy to reposition
- Low 19 inch height suits step-up style movements
- Vinyl pad wipes clean
- Lighter frame may feel less planted under heavy loads
- Only available in black
Performance notes
The alloy steel frame keeps total weight to 18 pounds, considerably lighter than many flat benches, which trades some stability under heavy load for easier repositioning. The 19 inch height sits lower than some benches, worth checking against your own seated or step-up exercises.
