12.5kg Hex Dumbbell Overhead Triceps Extension

The Overhead Triceps Extension is a highly effective movement for triceps development using minimal home gym equipment. With a single 12.5kg hex dumbbell, this exercise supports strength gains, calorie burn, and functional fitness, making it a core movement within the Nova Gym Box training system.

Muscles Worked

Primary muscles: Triceps brachii (long head).

Secondary muscles: Shoulders.

Stabilisers: Core, upper back.

Form and Technique

Maintain a neutral spine, brace the core before each repetition, and move through a controlled range of motion. Tempo should be deliberate, prioritising muscle engagement over momentum.

Calories Burned

Expect approximately 6–10 calories burned per minute depending on bodyweight and intensity. When included in circuits, energy expenditure increases significantly.

Progressions

Increase difficulty by slowing tempo, adding pauses, increasing repetitions, reducing rest periods, or pairing this movement with other Nova Gym Box equipment such as resistance bands.
