Leg lift crunches strengthen the lower abdomen.

That means tons of crunches won't eliminate belly fat. But you can strengthen the muscles in your core to give your stomach a more sculpted look and feel, especially if you clean up your diet and add in other cardio and strength training workouts.

They're far from easy, but leg lifts (also called abdominal leg raises) are a great way to strengthen your midsection, hip flexors and obliques. Burn out your core and give these leg lift exercises a try during your next workout.

How to Do a Leg Lift — the Right Way

Core
Lie on the ground with your legs out straight, arms at your sides. You can place your hands under your tailbone for more support. Brace your core and root your lower back into the ground. Raise your legs straight up toward the ceiling. Lower your legs back toward the ground, keeping your lower back in contact with the floor. Hover your feet just above the ground before rising for the next rep.

Tip While you perform this exercise, there are a few safety tips to keep in mind, says K. Aleisha Fetters, certified strength and conditioning specialist and author of Fitness Hacks for Over 50.
Keep your lower back on the ground at all times. Only lower and raise your legs as far as you can keep the back on the ground. Brace your core throughout the entire exercise. Perform as many reps as you can with good form and build from there.
Leg Raises Benefits It’s a common belief that leg lifts strengthen the lower abdominal muscles (which are not actually a separate muscle, by the way, just a part of your rectus abdominis — the “six pack” muscles). It might very well feel that way, as the exercise does make the lower part of your abs burn after just a few reps, but your abs aren’t the only body part putting in work.

A lot of the work in your leg lifts actually comes from the hip flexors, Fetters says. Your iliopsoas and rectus femoris are two hip-flexing muscles that lie deep in your lower abs, and they get plenty of attention with this exercise, according to ExRx.net.

Leg lifts can help you stabilize your lower back, boost your core strength and improve your posture and alignment, according to a February 2016 study in the Journal of Physical Therapy Science. Even more importantly, the exercise can help make you more injury-resistant.
