3. Operating Instructions
The Marcy Olympic Weight Bench offers versatile workout options. Always ensure the bench is on a stable, level surface before beginning any exercise. Adjustments should be made carefully and securely locked into place.
Adjusting the Back Pad and Seat:
The back pad and seat can be adjusted to 5 different positions (incline, decline, and flat) to target various muscle groups. To adjust, locate the adjustment pin or lever beneath the back pad/seat, pull it out, reposition the pad to the desired angle, and release the pin to lock it securely. Always double-check that the pin is fully engaged before use.
Using the Leg Developer:
The integrated leg developer allows for leg extensions and leg curls. Load Olympic-sized weight plates onto the 2-inch weight post. Secure plates with a collar. For leg extensions, sit on the bench with your shins under the top foam rollers and your knees aligned with the pivot point. Extend your legs upwards. For leg curls, lie face down on the bench with your Achilles tendons under the lower foam rollers. Curl your legs upwards.

- Cleaning: Wipe down the upholstery and frame with a damp cloth after each use to remove sweat and dirt. Use mild soap and water for deeper cleaning, avoiding harsh chemicals.
