I thought it would be useful to start a thread where people can post progress updates or just stories where they've improved.
I've been doing F1/H1 for about a year now, in that time my flexibility/mobility has improved remarkably (which has been my biggest hurdle), I'm also a lot stronger and leaner than when I started.
I'm on PE:3/4 for most elements with a few of the tougher elements holding up progress.
Manna and single leg squats have been the slowest the progress though they're quickly becoming my favourite elements.
My success story is my straddle up, every week my form improves, earlier this week I had to pause mid rep in shock at my new ROM.
