FAQ
Does the rubber coating have a strong smell when new?
Some rubber dumbbells may have a mild rubber odor when first unboxed, which is completely normal. This typically dissipates within a few days, especially if stored in a well-ventilated space. Wiping the heads down with a damp cloth can also help speed up the process.
Are these dumbbells suitable for use on hardwood floors?
Yes - the rubber over-mold heads are specifically designed to protect flooring surfaces and reduce noise on impact. That said, using a rubber gym mat under your workout area is always a good practice for added floor protection and stability.
Why does the handle diameter change at 15lb?
Lifeline sizes the handles to match the weight of the dumbbell - lighter dumbbells use a 28mm handle for a comfortable grip at lower loads, while 15lb and heavier dumbbells step up to a 34mm handle to provide a more secure, controlled hold as the weight increases.
Can these be used for push-ups and planks?
Absolutely. The hex head design keeps the dumbbells from rolling, making them very stable as push-up handles or plank supports. This is one of the standout advantages of hex-shaped dumbbells over round-headed alternatives.
Is a rack or stand included with this set?
A rack or stand is not included with this set. If you'd like to keep your dumbbells organized and off the floor, a compatible dumbbell rack can be purchased separately.
