there are a lot of good suggestions here already!
but i'll jump in and say that i've been following blogilates on youtube for years and done at least one of her videos every day
there's a range to pick from from beginner to advanced and everywhere in between

she always felt very real for me and i felt like i could sometimes match her fitness and find her very inspiring
and if i can't really be bothered one day there are some videos that are five minutes long but i still feel it the next day, and they can range anywhere up to 30 mins too

yeah so she might not be everyone's perfect workout but following her videos is mine!
