You can edit all the default text associated with an exercise or injury.
Simply click on the default text and modify all text, sets and reps. See below.
Changing Sets and Reps, an exercise to a hold, or modifying the default text is done by clicking on the field you wish to edit.
The numerical boxes will only allow 1 number entry per box. ie it will not allow 3-4.
Once clicked, the edit screen will open and allow you to change the sets, reps and toggle the reps to a "hold" if required.
Once finished, just click "save".
Remember you can add your own generic text in the box at the bottom of the page as well
