## Long description

OUTLINER Outliner 20Kg Cast Iron Dumbbell Set is a 20 kg adjustable dumbbell set constructed from cast iron. The set includes a pair of threaded handles and multiple weight plates that can be combined to create a range of loads up to 20 kg per assembled dumbbell. It is intended for general strength training at home or in a compact gym space and supports common resistance exercises such as presses, rows, curls and lunges.
Advantages
The cast iron construction provides durable, long-lasting weight plates with a compact profile that saves space. The adjustable design allows gradual progression by adding or removing plates to achieve the desired resistance. Threaded collars secure plates during dynamic movements, and the set’s simplicity makes it easy to switch loads between sets without requiring large storage or multiple fixed dumbbells.
Suitable for
 Home and garage strength training
 Full-body workouts including presses, rows, curls and lunges
 Progressive overload routines and adjustable resistance training
 Users who need a compact, space-saving weight solution
Key specifications
 Total adjustable weight capacity: 20 kg (set maximum when plates combined as intended)
 Material: cast iron weight plates and metal handles
 Handle type: threaded bar with screw collars for plate security
 Plate style: round cast plates for compact storage
 Intended use: adjustable free-weight training for home or small gym
How to use
Assemble the dumbbell by sliding the desired combination of weight plates onto the threaded handle and secure them with the screw collars. Ensure collars are tightened before performing any exercise. Use proper lifting technique for each movement: maintain a neutral spine during presses and rows, control the eccentric phase on curls and lunges, and adjust weight in small increments to match ability and progression goals. After training, disassemble and store plates and handles in a dry place to reduce corrosion risk.
Usage recommendations
Start with lower plate combinations to confirm form and joint tolerance, then increase load gradually. Inspect threaded collars and handle threads regularly for wear or loosening. Use gloves or chalk if grip slip becomes an issue, and avoid dropping the dumbbells to prolong the life of the cast iron plates and protect flooring.
