What's up guys, Jeff Cavaliere here from athleanx.com. Today, I want to show you one thing to do before every one of your ab workouts, especially if you're somebody that has a hard time feeling your abs work or tends to feel it more in your low back. That's because you're relying too much on your hip flexors to do your exercises, and we need to fix that right now. We can fix this issue with reciprocal inhibition. This fancy term means that if we activate or contract a muscle that acts on the opposite side of a joint, we can turn down the muscle we don't want to work. In this case, we want to activate the hamstrings and glutes to inhibit the hip flexors from taking over in ab exercises. To do this, grab a foam roller and place it behind your ankles and up against your butt. Squeeze your glutes and hamstrings together, creating a sensation of everything being squeezed up and under. This action forces the hip flexors to shut down a little bit and allows the abs to do more of the work. Now, let's try a levitation crunch. Squeeze the foam roller and lift your shoulders off the ground. You should feel a stronger contraction in your abs. Do 10 reps of this exercise. Then, move on to a cross-body crunch, squeezing the foam roller and twisting your body. Do five reps on each side, totaling 20 reps. Finally, a bottom-up movement, squeezing the foam roller and lifting your legs. You'll feel your hamstrings and glutes engage while the hip flexors are minimized. Do 10 reps. When you transition to your full ab workout, remember to avoid using your hip flexors for lower ab movements. Limit the range of motion so that the pelvis and legs move together....
