Shake it up: can a Flexi-Bar make you faster and stronger?
NCT ID NCT07574788
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether using exercise bars like the Flexi-Bar or Theraband Flex-Bar can improve how well your arms sense position, react, and perform power moves. Forty-five healthy men aged 18-35 will do a single session with one of three tools (Flexi-Bar, Theraband Flex-Bar, or a rolling pin as a sham). Their proprioception, reaction time, power, and upper extremity performance are measured before and after. It's a small, early-stage trial in healthy people, so results may not apply to athletes or those with injuries.
