Push Your Partner!
There is something unique about working out with a partner or team. It tends to lead to you pushing harder than you normally would on your own. For some reason, we seem to be more motivated to not let others down. When it comes to quitting on ourselves, we're perfectly comfortable with the feeling. However, letting someone else down doesn't feel so familiar or acceptable.
That's just my random explanation of this phenomenon. Regardless of how true it is, come experience the extra push involved with a partner workout.
Love you bye!
