Thanks for all the replies. All really helpful.
Think I’m going to hire a concept 2 for a few months to see how I go. My partner is skeptical about me keeping it up (I held my tongue over his cross trainer gathering dust in the spare room).
Good points raised about technique and warm ups. I’ve only had 5 goes on a machine and the resident gym instructor gave me a 5 min demo so will need to read up on that.
