There are a few things you can do to freshen up your bootcamps for the week in addition to the other suggestions. One, you could play with interval times. 30 seconds, 45 seconds, 60 seconds and tabata structures all work well for bootcamps. Play with rest times, and if you have an advanced crowd, make the rest times shorter.
Another idea is to have a purpose, or focus for the week (example–upper body strength moves with plyometric legs like squat jumps or lunge jumps). You can still have a full body class while making them focus on certain muscle groups for the week. This will give them something to focus on for the day/week.
Or, only pull out certain pieces of equipment that week as a focus. It will mix things up and work muscles in different ways.
Hope some of these ideas help.
