Crossovers (abs)
Crossovers train the obliques hard by combining rotation with a crunching motion, hitting the sides of your abdominal wall more directly than a straight-ahead crunch. Lying on your back with knees bent, curl your shoulders up and rotate to bring one elbow toward the opposite knee while extending the other leg out. Alternate sides in a controlled rhythm, keeping your lower back pressed into the floor throughout.
Modified Knee Raises (abs)
Modified Knee Raises isolate the lower abs with an easier range of motion than a full hanging or straight-leg raise, making them a good stepping stone toward tougher lower-ab work. Sit on the edge of a bench or lie on your back with knees bent. Curl your knees up toward your chest by contracting your lower abs rather than swinging with momentum, then lower back down with control until your feet are just short of the floor before repeating.
Seated Knee Raises (abs)
Seated Knee Raises strongly target the lower abs with a compact range of motion, making them an efficient tool for building a six-pack. Sit on the edge of a bench or chair and lean back slightly, holding the edge for support. Draw your knees up toward your chest using your lower abs, then extend your legs back out without letting your feet touch the floor between reps.
