Hi, I’ve been using FitSociety for a while now to track my workouts. I try to increase the repetitions or weight every week. If I have an off day or week, I can't manage this, so I occasionally go down. Currently, I can only see how many repetitions I did in my previous workout, not everything. Could you look into adding some kind of personal best to each exercise so I can look back at every workout? Thanks!
