An Instagram fitness reel by calisthenics creator BRAWNX argues that looping a resistance band under the feet during a dead hang lets you hold longer, that continuous breathing gives you the strength to maintain the hold, and that this progression can build grip-strength hang duration to one minute.
The reel's core technique — band-assisted dead hangs as a regression to build grip endurance — is consistent with standard progressive-overload coaching practice and is likely reasonable general guidance. However, all automated research passes returned zero validated sources, the breathing claim is causally overstated as phrased, and the specific one-minute outcome is an uncited creator heuristic; the claims therefore remain unverified in this pass rather than confirmed or refuted.
