Number of reps with "+"

In the workout guidelines, the AI suggests that no matter the target number of reps, I should always be doing as many reps I can muster with good form and common sense. Sometimes I just forget to grind out the extra reps, and just set my mind on achieving the indicated number of reps. 

It would be helpful if there was a plus sign after the target number, e.g. '8+' instead of just '8'.

This is a minor thing but should be easy to fix, also, and it would give the app more polished feel.
