Core Armor is a core workout built on a simple but effective pattern: hold, move, hold. Every exercise is bracketed by a 10-count hold that makes your core stay braced before and after each movement. The climber taps train your shoulders and deep core to stay stable while your legs move. The side bridges work the muscles along the sides of your trunk - the ones that keep you upright and protect your spine under load. The knee-to-elbow crunches bring in flexion and rotation together, connecting your upper and lower abs into one coordinated effort.

The holds are not rest. They are the point. Each 10-count forces your core to maintain tension rather than switch off between reps, which is what builds the kind of core strength that actually holds up under pressure. Three different positions - on all fours, on your side, on your back - mean the whole core gets trained, not just the front.

Core Armor builds a strong core from every angle. The kind that protects you, holds you together and doesn't quit when things get hard.
