Thanks for the responses guys!
I'm not too bad at holding down chords - it's mainly changing chords that involve moving anything more than 1 finger. Just don't seem to develop that all important muscle memory. I struggle to keep up at 50% speed on the tutorials and can't really play anything over 30 BPM even after weeks on a single lesson. I have an acoustic with a fairly low action and it feels comfortable plus an electric that I prefer because I'm ashamed to plug in and it's quieter. My practise is focused and regular and I'm not even that frustrated, just an awful player!
