Physical ability is going to be different for everyone. Muscles do have a great memory. I'll be 70 this year and working on finger picking which requires both hands finding strings.
A trick I believe I learned here at GT is to set one finger of the chord, try that for a while, add second finger and so on and so forth until you have the chord fingering down. You don't strum the guitar, just set your finger down in the chord shape. Rest them there for a few seconds. repeat..
I like to start with Am then E.. so I can practice changing back and forth between the two.. I may be wrong, but I like to do the open chords (cowboy chord) for my warm ups.
Keep at it, you be surprised at how fast it comes after a while..
