It isn’t easy getting fit. There’s a lot to learn: Your workout itself, whether the number of reps you do matters, and then there’s all the gym and exercise lingo you’ve never heard before. Say no more. We understand, and we’ve put together this primer to help.
Keep in mind that fitness jargon is endless, so this list isn’t comprehensive. It is made up of many terms that you may have heard before but didn’t understand, or heard a trainer toss around.
Big jumps are OK if you’ve dipped under your baseline; tread cautiously at any number above that.
Paying attention to the numbers is important if you’re trying to work up to a longer distance or follow a training plan for a goal. If you just run the same amount every week, you can safely ignore the math.
