Bootcamp - How do I log as exercise?

I go to a bootcamp M-W-F and work out for 35 minutes plus 5 minutes warmup and 5 minutes cooldown. We do sets of exercises for 30 seconds to two minutes; some cardio & some strength - that's a lot of different exercises in 35 minutes. The routine is different every day. I want to log in my time but I can't possibly list each and every exercise we do. ANY SUGGESTIONS?
