Actually, most analysis suggests utilizing a chilly plunge earlier than or after a exercise can truly make it more durable to construct muscle and achieve power. 

On this article, you’ll discover out why that is, uncover the greatest time to chilly plunge to keep away from these points, and extra.

What Is a Chilly Plunge?

The examine had rugby gamers use cryotherapy earlier than coaching, and whereas some confirmed a rise in T, there are a number of causes to be leery of the outcomes.

First, it included solely 12 males, and never all of them noticed a rise. Second, it used cryotherapy at -220°F, which is far colder than a typical chilly plunge at 60°F. Third, it measured testosterone ranges at totally different occasions of the day for various contributors with out accounting for pure each day fluctuations.
