Ab Forge is a focused core workout that keeps your abs working almost the whole time. Flutter kicks train the lower abs, hip flexors, and deep core muscles while asking you to keep the legs controlled and the midsection tight. Knee-to-elbow crunches add rotation, which brings the obliques into the work and helps build strength through the sides of the waist. The hold positions increase the challenge by making the abs stay active without rest, so the workout builds strength, endurance, and control at the same time.

This routine is especially good for improving core endurance, lower-ab strength, and body control. Because the exercises stay close to the floor and repeat similar movement patterns, it is easy to follow but still demanding. The challenge comes from keeping good form as the abs get tired. Try to keep your lower back supported, move with control, and avoid pulling on your neck during the crunches. Ab Forge is a great choice for days when you want a direct ab workout that feels simple, strong, and effective.
