Does the 'ideal' apply to me?

I came back to the gym after 3 months, weighed myself and then did it again 2 weeks later. I've only done cardio like spin and some mat exercises.

My results show I put on weight and dropped the bf%, so does this mean I lost fat and gained muscle? Surely not in 2 weeks when I haven't even done weights other than kettlebells? I'm basically trying to get my head around what this means.
And it's clear that I am not in the 'ideal' range, but does this apply to me as someone who exercises daily and will burn more fat than the average person? I'm the right weight but am under body fat so is that alright? I plan to gain muscle when I start doing more weights.

    If you're getting your body fat percentage from a smart scale, be aware that it's only a very rough guess.

    I doubut its muscle. how did you measure your fat %? if you put on weight its most likely water retention.

    I would not really take a lot from a bodyfat% changes unless doing it under extremely controlled conditions, and even then its very suspect.

    As far the "ideals" and charts and all that. Who cares.

    1. Are you healthy?
    2. Is your body looking how you want it to? If so then yes you are ideal if you are also healthy. If not then keep moving in that direction.

    Oh okay, it was one of those big scales at the gym. They have them in Boots as well of you're from the UK. Even if it is rough, I would understand 1% off but 3%?!)

    It means that the BF measurements are not at all accurate. I've heard they can be off by as much as 10% in either direction. Absolutely meaningless. Just keep doing your plan and you will make progress.

    Oh I see I see. This is more reason to ditch the scales then I guess. I need to start going by tape measurements and progress photos more then.

    those scales are highly inaccurate. you'd be better off doing a dexa scan,or a bod pod(hydrostatic weighing).

    When I had my DEXA (which people consider more accurate but still is not super accurate for individuals) I was told not to return for a re-scan for at least 3 months as it generally takes that long for measurable results. I wouldn't count on the accuracy of short term measurement changes from a scale.

    The one I used to use I could get on it, get off, drink a glass of water, and that water would change it a few %.

    Those fluctuate a ton and are not accurate. If you use the same one at the same time every day it will show a trend, but still can fluctuate a lot day to day.

    In 2 weeks your BF% won't change significantly at all, and you certainly won't build any measurable amount of muscle (especially for a woman doing mostly cardio).
