Press firmly and press the switch to adsorb on the ground. Matters needing attention: 1. The ground needs to be clean and smooth 2. There must be no gap on the ground, which will reduce the adsorption force. 3. When the adsorption force is not enough, a little water can be added, and the adsorption force will be strengthened.

Works well!
This sit-up equipment works really well! It sticks to the floor and provides solid support for me to do my sit-ups. I use it on my wood floors, and it works there too.
