I did, too. I had no regime as such, just decided I wanted to be a bit more toned. I won't diet because ex-anorexic, but I did alter my diet slightly away from cream & butter in everything, more baked potatoes than dauphinoise iyswim.
I recognised that being toned creeps up you - you do exercise for months, thinking nothing's happening, then all of a sudden you see yourself in the mirror and think "Oooh, look at that! I'm toned!"
I did bits of anything, really, as long as I had to push myself for the last few minutes: longer or faster walks, assorted videos, swimming, dancing, some yoga, some weights, tried out various classes. I ended up needing something else for that final few minutes' push, so that's when I joined a gym and learned how to use the machines properly.
As I rarely weigh myself, other people noticed before I did that my clothes were sitting better (I wish people didn't feel so free to comment on your body size & shape, but that's another thread!) I eventually dropped two dress sizes and it's definitely true, clothes hung a lot better. It took maybe 18 months in all. I just kept on doing much the same for the next ten years. Stayed the same size, had excellent CV stats.
Am now shapelessly squishy again 😂 Can't repeat my non-programme due to ME-CFS ... so I would add a caution to limit "pushing yourself" if it's becoming an obsession. That feeling of physical mastery can be addictive! Worry about that later, though - for now, just enjoy yourself 💃
