In some international locations, firefighters are additionally required to prepare with weighted vests to organize them for the calls for of their job.

Extra not too long ago, individuals have been utilizing weighted vests throughout exercise challenges, as a part of CrossFit and even whereas working, within the hope of boosting their health. And analysis backs their advantages.

It will likely be necessary for extra analysis to be completed which seems at how weighted vests could profit many various teams of individuals.

Potential dangers

However to keep away from the chance of damage, ensure you begin with a light-weight weight at first (round 2-3kg) and steadily enhance the load over a number of weeks as your physique turns into accustomed to it. This can maximize the advantages that weighted vests afford whereas limiting the chance of damage from pushing too arduous too quickly.
