You’ll know you’re properly wearing a weight lifting belt if you’re breathing into it (expanding your stomach/core into the belt and then bracing against it). You should feel like its squeezing
A weightlifting belt helps to support your lower back by allowing you brace your core against the belt giving you the ability to generate more power & stability
A lifting belt should always be worn when lifting heavy. Heavy is uniquely dependant on your strength levels. We recommend beginners & advanced athletes who perform heavy lifts to use a lifting belt
Measure your waist & use the size chart below:

The 13mm belt is simply a little thicker & will last you longer than the 10mm belts because it's designed to provides additional support

Your belt should NOT be washed. If it gets dirty you can rub it with a damp cloth
You can do any heavy lifts with the belts but the main exercises the belts are used for are:
Squats

The smell from the belt comes from the leather mixed with the resin from the edges of the belt. In order to remove the smell let it air outside (without getting it wet) & with use in the gym it will go away
