Overload is not a circuit - it is two exercises done as straight sets, with equipment, and that changes the rules. Cable crunches for 3 sets of 10, then decline sit-ups for 3 sets of 10, with up to 90 seconds rest between sets and exercises. This is the abs-with-resistance session, and the name is the method: progressive overload, the principle that muscles grow by being asked to move gradually more weight than they are used to. Your abs are muscles. They respond to the same math as everything else.

The order is heaviest first. Cable crunches let you load trunk flexion directly - the weight stack sets the resistance, so you work in a range bodyweight can never reach, while you are freshest. Decline sit-ups follow: the angled bench extends the range of motion and makes your own torso a heavier lever than it is on flat ground, bridging the gap between the cable's external load and ordinary floor work. Three sets each with generous rest is the strength format, not the endurance one - the 90 seconds exists so every set is done with full force, and cutting it short only subtracts from the next set. Progress here means adding a plate or a rep over the weeks, not rushing the clock.

Kneel for the cable crunches with your hips fixed, and curl your ribs toward your pelvis - the movement is a contraction of the abs, not a bow from the hips, and the hip angle should barely change. Choose a weight that makes rep ten deliberate, not desperate. On the decline bench, lower yourself under control for a slow count, keep your chin off your chest, and come up by curling rather than yanking - if you need to swing your arms for momentum, the angle is too steep for today and that is useful information, not failure.

Bodyweight built the foundation - the weight stack is how the foundation gets a second floor.

Make it Harder: Add weight to the cable, not speed to the reps.

Make it Easier: Reduce the decline angle of the bench or do the sit-ups on flat ground.
