This is similar to the Bicep Workout I posted yesterday. It follows the same concept: complete each lettered circuit 4x. Go from one exercise to the next with no rest. Catch your breath at the end of each ab exercise before repeating the circuit. ✅ EX: do the exercises in "A" back to back with no rest. Rest after you complete the ab exercise. Repeat "A" 3 more times for a total of 4 total rounds.
