Default [Q] Exercise tracking only for moving activities?

I was checking out the Fit and Gear 2 in BB today and the exercise tracking/coaching apps seemed to only be set up for various activities that involve movement such as jogging, hiking, and biking. I was hoping to use it to track gym workouts (whether weightlifting or aerobics workouts), but there didn't seem to be a "general" exercise setting that simply tracked heart rate and let you know if you were above or below a target. Did I miss a mode somewhere?

I suppose that I could put it in one of the "running" or "biking" modes and just let it believe that I was actually going somewhere, but a review of the fit mentioned that it won't even start a session in biking mode if it can't get a GPS lock. I'm guessing that the running mode might get bored and cancel out if it didn't detect pedometer inputs.

Has anyone tried using it for simple general-purpose heart rate monitoring and tracking?
