Belts are a tool for your sport.
They allow you to brace better, especially with heavy weight.
There are different suggestions for when to put a belt on.
I don’t think you can go wrong putting it on when you get to 65% or above on your BIG lifts.
You don’t need for assistance work.
Good belts are not cheap.
We suggest the following:
SpudInc Pro Deadlift belt-available at TPS-made in USA
ELiteFTS P3 power belt-made in USA
Cardillo Power Belt-Made in USA available at ANC in Everett.
