Q&A

Q: Are the 37.5 lb dumbbells well balanced?
A: Yes — they are precision-engineered for even weight distribution and stable handling.

Q: Will the round shape roll away?
A: Minimal rolling occurs, and proper storage on a rack ensures safety and convenience.

Q: Are the handles comfortable during extended sessions?
A: The medium diamond knurl offers a secure grip without excessive harshness on the hands.

Q: Will the rubber or chrome finish wear over time?
A: No — the virgin rubber coating and industrial hard-chrome handles are built for durability and long-term use.

Maintenance Tips
  • Wipe rubber and handle surfaces with a mild soap-and-water solution after workouts.

  • Store on a rack to prevent unnecessary wear or deformation.

  • Avoid prolonged sunlight exposure and extreme heat to maintain rubber quality.

  • Brush the knurling periodically to remove sweat or debris buildup.

  • Do not drop from height to protect coating and structural integrity.
