Consider the floor tiles at home, whether it is a wooden floor or a tile. It is recommended to buy rubber-coated dumbbells, which will better protect the ground.
If stainless steel or electroplated dumbbells are placed on the ground, they will easily slip off. There are also rubber dumbbells that can be used for push-ups and crawling (Spartan style, which is very effective for training upper body muscles)
When buying dumbbells, you must buy detachable dumbbell pieces that can be added and subtracted freely.
If possible, buy a dumbbell stool, and the comprehensive training effect will be more obvious.
