Emily, don't be worried about what the numbers say! If you want to know for sure, test more, like others have recommended. If you just want to increase your "buff"ness, up your weights and to interval training when you do cardio. If you're happy, don't worry about it. You sound *very* fit.

And you're an inch taller than me and I outweight you by 25 pounds! Everyone says I'm tiny, but I know I'm not. I am happy to say that I know I have a fair bit of muscle, but it is hiding very well under a goodly layer of fat. Health issues are keeping me from really attacking it with serious exercise, but time will allow it.

I do have one of those body fat scales. It places me between 28 and 30%. I can see from week to week just what the trend is.

One interesting note. Recently I had a very good exercise week. 6 Intense exercise days that including spinning, snowshoeing, kickboxing and brisk walking (kickboxing counts for weight training in my books). That week I gained weight, gained fat %age, and muscle mass either went down or stayed the same. The following week, I had difficult health issues and had to rest a lot. That's when I saw the benefit from the week earlier. Muscle mass went up, fat %age went down, weight went down slightly.

Maybe, just maybe, you actually need to rest more so your body can rebuild that muscle?

Just a thought.
