1. Hanging Leg Raise Or Knee Raise
There are many reasons to like leg raise variations, but one is their scalability. You can start doing bent knee raises in the Roman chair or ab straps to focus on the lower core, work up to straight leg raises, and then move to a hanging bar. By the time you can do full straight-leg toes-to-bar raises, your entire core will have strength for days.
2. Machine Crunch
In our opinion, ab exercises with added resistance don’t get enough love! They spur growth in the fast-twitch fibers like almost nothing else, and they can really build up the “bricks” of your six-pack. By adjusting the load, you can also train to failure at just about any rep target you want. A pin-loaded machine also works well when doing dropsets.
3. Cable Pallof Press
This increasingly popular movement trains your abs to do what they’re supposed to do: stabilize your skeleton. Pallof presses serve as an anti-rotation movement, meaning the body is actively fighting rotation throughout the motion. By utilizing exercises like this, you can increase core stability in various planes of movement and reduce likelihood of injury.
4. Kneeling Cable Crunch
The primary strengths of this crunch variation are its versatility—you can do it on any cable stack—and the way it allows you to use any level of resistance to train for a target rep range. Still, lots of people perform them wrong.
5. Decline-Bench Crunch With Medicine Ball
Decline-bench crunches amp up the challenge by increasing the range of motion over standard crunches, and you can dial up (or down) the degree of difficulty by adjusting the angle of the bench. Adding a medicine ball or weight plate against your chest adds a further level of customizable resistance. This also allows you to manipulate where you want to fail: low, medium, or high reps.
Yes, a leg exercise made the top 10 list for abs. Anyone who has ever pushed their potential in the squat knows exactly why! Sure, squat variations work the legs and lower back, but they also crush the abs. Both front and back squats force your abs and spinal erectors to work overtime to maintain a neutral, upright position. If both were not firing at high rates, you’d fold under the weight or drop in a split second.
7. Decline Russian Twist With Medicine Ball
This harder version of the Russian twist works the obliques while requiring the upper abs to contract isometrically. To recruit the obliques, you either need lateral flexion (bending to your side), trunk rotation (twisting), or sucking in your belly. Doing your twists works the trunk-rotation function of the muscle, so really focus on the contraction. Try to get a little crunch on either side after the rotation to up the ante.
