Here's the full progression.
I dig how our 2 chord flows right into our 5 chord. rotate your fretting hand towards the headstock slightly to make that transition more ergonomic.
I also love that our 2 chord & 1 chords have a single note difference between them.
Groove on!

Here's the full progression.
Our 2-5- hinges on that Bb on string 1, with just a single string move for finger 2. From there we slip finger 1 from string 1 to string 2 & add in our pinky to grab our 7(E) on string 3. Easy peasy and groovy.
Play on!
