Barbell complexes would be a good place to start, but that's what I'd call it, barbell complexes and not crossfit exercise.
1. Power cleans x5
2. Front squats x5
3. Deadlifts x5
4. Power clean from hang, into military press x5
That would be a starter for 20 reps total, counted as one set. Rest for 4 minutes before repeating for 4 more sets, for a grand total of 100 reps.
Im not sure have the deadlift in a circuit is wise
