Just like the exercise history/volume from the previous workout is visible for each exercise, make the past comments visible during the workout as well. I encourage clients to take notes on how things feel. This allows clients to know if what they did previously was too easy, too hard, needed a different cue, or if they just felt worse that day for whatever reason and know they can push harder in the following workout. The volume history is great, but the added notes context would be super beneficial.
