It would be great to have possibility to have strength overview graphs and tables in dashboard. For example user would be able to select exercise and rep count - and you would be able to overview max weights for specified rep count (greater than or equal reps) over date range graph. Also table like view for selected exercises and their max weight over specified reps. This would help to better overview strength progression over longer period of times. And giving flexibility on selecting exercises for reports would let user to focus on the exercises which are most important for them.
