The 100-Calorie Finisher #02
Do 25 cals on the SkiErg at a sprint pace, then grab a barbell or dumbbell and do 25 thrusters (no weights? Try squat jumps). After your thrusters, get back to grips with the ski, but this time sprinting 20 cals before matching that with thrusters. Continue in this fashion, reducing your target each round to 15 cals/reps, then 10, followed by a final soul-searing 5 of each.
