FAQ
Are these dumbbells safe to use on hardwood or tile floors?
Yes. The rubber over-molded heads are specifically designed to protect flooring from damage and reduce noise on impact. They're a great choice for home gyms with hardwood, tile, or other hard floor surfaces. Using a rubber gym mat underneath is still a good idea for extra protection during heavy drops.
Why do the handle sizes change between lighter and heavier dumbbells?
Lifeline sizes the handles to match the demands of each weight range. Lighter dumbbells (under 15lb) use a 28mm handle diameter for a more natural grip on smaller hands and exercises, while heavier dumbbells (15lb and above) step up to a 34mm diameter to give you better control and stability when lifting heavier loads.
Can I use these for push-ups and plank exercises?
Absolutely. The hex shape is one of the biggest advantages here - the flat sides prevent the dumbbells from rolling, making them stable and reliable as push-up or plank handles. Many lifters prefer this over smooth round dumbbells for bodyweight exercises for exactly that reason.
Will the heads ever come loose from the handles?
Lifeline uses a high heat and pressure bonding process to secure the heads to the handles, creating a strong and stable joint. This construction is designed to hold up under regular, heavy use without loosening over time - unlike cheaper sets that rely on basic mechanical fasteners alone.
Does this set come with a rack or storage stand?
A storage rack is not included with this set. You will receive the 10 pairs of dumbbells (5lb through 50lb). A compatible dumbbell rack can be purchased separately to keep your space organized.
