A boot camp would be easy then. Up an Downs. High Knees. Sprints and you can even set up relys. Just make sure you rotate teams around so one team doesnt lose all the time. You can also make them carry dumbbells then sprint to a teammate and the teammate sprints back... repeat till all members have gone. You can extend this by then making it an all out race/jog to a further location. Then you have you standard push-ups, sit-ups, sqauts. I wouldnt bother with boxing gloves and pads unless you have 4 of each.
yeah....this sounds cool....and maybe fill the buckets with sand and sprint to a teeammate as well, you can incorporate the speed of filling the bucket and the farmers walk advatage of carrying the buckets to the next teammate.
