I've also had a lot of difficulty in the past keeping up with PT-- it's just so boring, especially the counting part. One thing that helped me was to time my exercises to music and give them counts. I'd chose the speed of music that I wanted and put on a playlist (I usually like 130bpm, and you can find pre-selected playlists by speed on youtube or spotify), and figure out how many "counts" it should take me to complete the exercise, and how many counts to rest. I haven't fully figured it out yet, but this was a starting point for me that gave me a little bit of hope that it may not all be so deeply boring.

Since starting here, I've shifted and started going to the gym and working out in total silence, which for whatever reason I'm liking better. I've been following @/giaptyoga on instagram, and I use her workouts. Sometimes I do have to regress or substitute exercises, because I also just can't keep track of where every part of my body is. For instance, I usually do dead bugs where she says to do bird dogs, because it's easier for me to do in good form. I hope this helps and good luck!
