This Tiny Attachment Could Break Your PR Plateaus – ISO Cup Review

Описание: Stray Dog Strength ISO Cups: https://shop.straydogstrength.com/pro...

This tiny rack attachment could break your PR plateaus. I’ve been using the Triphasic ISO Cups from Stray Dog Strength for a month across every push/pull day, and after integrating them into isometric holds, I’m confident these are one of the most underrated pieces of strength gear in the home gym market.

In this video, I break down how I use them on front squats, deadlifts, rows, and more—and share the science behind why isometric holds work so well.
