COVID-19 stealing your gains?
Make simple dumbbells from a couple of regular plastic bottles and some dirt/sand/water with this connector.
There idea of the chamfer in the middle is to create a tiny weak spot, so should the connector break, the bottles will remain closed and won't spill dirt on your favourite carpet.
