2-Move Abs is a minimalist core workout with a sneaky twist: everything is small, tight, and circular, so the burn doesn’t come from big reps, it comes from uninterrupted tension. You alternate between circle crunches and raised leg circles in short sets of 4, repeated again and again like a dial you keep turning up one click at a time. Circle crunches hit the upper abs and obliques with a controlled, scooping motion that demands precision, while raised leg circles shift the focus lower, forcing your pelvis and deep core stabilizers to stay locked in while the legs trace smooth arcs.

The transitions are what make it work: you’re constantly switching between “torso circles” and “leg circles,” so your abs don’t get to hide behind one pattern. When the legs move, your midsection has to resist sway and over-arching; when the torso moves, your hips have to stay steady and your ribcage has to stay connected. Keep the circles tight, keep the movement smooth, and think of it as carving clean lines rather than chasing speed. If your form starts to unravel, shrink the circle and slow down. The goal is control that feels deliberate, not a frantic wobble.
