So I started taking a Bodypump class two months ago and it may fit what you're looking for. It's a weights class that focuses on a lot of reps with smaller weights and does all the major groups. Usually you focus on a group for the length of a pop or dance song. The exercises are designed to be done with a weight bar, but I've adapted exercises using handweights (and two bottles of wine in a hotel room one weekend :D). The trick is that I can't point you at a specific YT channel because it's one of those that's supposed to be a paid class but there's a lot of sample videos on YT from people posting their teaching applications. This would be an example: https://www.youtube.com/watch?v=wWKt6C8VDFU
