Well, me. And given that most of the progress photos have someone asking abotu BF%, I’d say it’s at least of passing interest.
Prof: I’m actually quite skinny. Perhaps even laughably so.
Which leads me to telling you that it DOES NOT MATTER. Yes, many people ask that question. It doesn’t make the answer any more important. Guys getting into weightlifting worrying about what number they are at instead of the gains in strength they are making are not doing themselves any favors. It doesn’t matter what your body fat percentage is…not even in the slightest way.
The ONLY time this may be important is if you are dieting and the goal is to hold onto as much muscle as possible. Even then, however, it can set you back as body water held intramuscularly can also be counted as lean mass causing many to believe they are losing muscle when they may not be.
In other words, gain and forget what number you are. It means nothing for most people.
