What is the opinion of Reddit about the
Ader Leather Power Weight Lifting Belt- 4″ Red/White/Blue (Small) 24-32″?

Get the straight-cut leather belts on amazon if you’re on a budget. This one is USA colored, so guaranteed gains. They’re worth it, increase core engagement, can add ~5-15% to your SQ and DL while helping with stability/safety under high weight. But it only makes sense if your squat mechanics are pretty solid; otherwise the priority is fixing mechanics.
