Help needed with Caroline Girvan workouts

[Claymorekick]

I am looking to start using Caroline Girvan's workouts - I have watched some and think they will suit me. I am just not sure which ones to start with.

I am an experienced (overweight) exerciser but definitely prefer lifting weights to cardio but appreciate I have to do some cardio so am ok with short bursts.

There seems to be quite a few series (which is my preference - to work through an entire programme rather than random workouts) so which series is best? Is there one that is not quite as advanced as others?

Any advice would be welcome 🙂

I did the Epic beginners first, but then was recommended to try Iron which is largely weights and quite a steady pace, not tricky moves. I'm using much smaller weights than she does - roughly 1/3rd - and have to modify push-ups as I can't do proper ones, but mostly it's ok. (I'm small and 62 though)
