Sorry, but you will NEVER find me putting bench press. My experience with the bench press is that even if you have perfect form, sooner or later, provided you go heavy, it's going to mess up your rotator cuff. I do heavy lifting and I just won't touch benching.
just creating a proper fire would be enough: walking, chopping, lifting/squatting, breaking branches, carrying, dragging (pulling), if it's really heavy then also semi-lunges are included. Then when you want to make sure the fire is going you have to do quite some squats, semi push ups (to blow air), pushing and pulling.... then bringing heavy stones to secure the fire.
but in terms of "real" exercises:
1. push up - the queen of them all.
2. variety of punching movements (esp. with a small weight)
5. sprints/variations of jumping rope (with high knees, butt kicks etc.)
