Stat tracking is a great way to measure your results over time, however if you want to get in the gym and work through your workout without entering stats you can turn them off by doing the following:
1) Swipe Left to Right to open the App Menu
2) Select Settings
3) Toggle the 'Save Stats for Drills' option off
4) Hit the 'Done' Button at the top right
The user will now not be prompted to enter stats at the end of each drill during a workout.
