While התעמלות

means exercise, the Hebrew word for fitness is כושר

.

For example:

זהו, השנה אני נכנס לכושר.

That’s it, this year I’m getting fit (going into fitness).

Someone who’s already accomplished this is בכושר – in shape

.

You may have noticed that כושר

has the all the letters of the Hebrew word for kosher – כשר

, and the two words are in fact related: something kosher is “fit” for consumption under Jewish law.
