Always keep the Concept # / Chapter in mind as you do each exercise.
In general you will be doing:
1 minute ON (work time) X 3 ROUNDS
:30 seconds REST
Your choice to do them back-to-back or as a circuit.
For Concept #1, you will do 3 ROUNDS of Wave Unload - back-to-back, then move to the next movement in this concept.
OR, you do Exercise #1 (Cat/Cow) before this move, Exercise #2 (Wave Unload), etc. and repeat the circuit 2 more times.
