Do free divers wear weights?
When I started freediving, I asked the same question nearly everyone does. … Freedivers wear lead weights to offset the positive buoyancy of their bodies and their wetsuits. To freedive comfortably, we use enough weight to help us descend to the point our lungs and wetsuit compress to the point we achieve buoyancy.
What are dive weights made of?
Diving weights are made from lead. This is a high density material that provides a heavy weight in a compact, easy to carry form. To protect the lead from corrosion often lead weights are coated with plastic and this can make them less abrasive on wetsuits.

People do die freediving, but Mock-Bunting says every event he’s attended has been closely monitored by safety divers and doctors.
How do free divers breathe?
Many freedivers use a technique called “lung packing.” They take the deepest breath possible, then use the epiglottis to hold the throat shut and take in a mouthful of air with fully puffed cheeks. Using the tongue as a sort of rake, the trainee attempts to shove the air from the mouth into the lungs.
