As someone who starts their workouts from the Apple Watch rather than the phone, I’d love to be able to see what the last weight I used was for each exercise. When I start my set, it would be awesome for the rep/weight to be “pre set” for each workout based on what my last numbers were. As someone who is still getting use to what my normal weight numbers are for each workout, it would be really convenient to not have to guess or check my phone to see what I last used for each exercise.
