Purpose:
They increase intra-abdominal pressure and core stability, which can help in safely handling heavier loads and potentially reduce the risk of injury during lifts.
When to use:
Many strength coaches recommend considering a lifting belt once you can squat around 1.5 times your body weight or deadlift 1.5 times your body weight, although this is a general guideline.
How it works:
It physically supports the core muscles and serves as a mental reminder to engage them during lifts.
