I often have the question too about how I track multiple strength exercises without keying them in individually. I usually do one of two things -- either put it in as a custom exercise ("Seventeen strength training workout") and enter the time, or I put it as circuit training -- not quite accurate since I don't necessarily keep my HR up, but it works for me.
Don't forget that tracking is mostly for you -- Spark doesn't DO anything with the information. Your calories are computed based on the amount you say you will exercise per week, not how much you actually do.
