How to use

Select the required weight configuration and ensure the locking mechanism is secure before lifting. Use the dumbbells for controlled repetitions of exercises such as dumbbell curls, shoulder presses, chest presses (on a bench or floor), single-arm rows and goblet squats. Maintain proper posture, engage the core, and perform movements with controlled tempo to reduce risk of injury. Inspect the cast iron surfaces and threaded connections periodically for wear and re-tighten as needed.

Usage recommendations

Start with lighter loads and focus on technique: perform a short warm-up, choose a weight that allows 8–15 controlled repetitions, and increase load gradually as strength improves. Store the dumbbells in a dry place to prevent surface corrosion and avoid dropping them on hard floors to protect the product and surrounding surfaces.
