Have started an email with ring with a few friends where we all share our workouts. Two of my favorites are below - both quick and high impact.
8 x 100 yd flat out sprint bookended by 25 pushups on one end and 10 burpees on the other
4 x 100 flat out sprint followed one of four exercises - 50 lat pulldowns, 50 situps, 50 pushups, 50 squats
