Or apps?
I've seen a few but they have poor sound, bad camera angles, annoying presenter (I realise this is personal), or they're just not achievable for a beginner like me.
Lots of them start off with that move where you lie down flat, arms over your head and sit up without using your arms to push up and saying OOF - it's just not going to happen here for a good while yet!
So, any recommendations please?
