Thicker bar = greater motor-unit recruitment.
A standard 28mm bar barely engages your forearms or grip stabilisers — the load bypasses your lower arm and goes straight to the larger movers. Forcing your hand to clamp a 50mm engineered diameter recruits the forearm, bicep and grip from the very first rep. This is the mechanism thick-grip training has been built on for decades, now executed in a premium engineered grip.
