What are Lying Leg Raises

The lying leg raise is a great core exercise that can strengthen your abdominal muscles and develops six-pack abs. Whether you want to improve your aesthetic appearance,  balance, or enhance your overall physical activities, your core plays a key role in executing these tasks. This exercise will require you to lie on your back and lift your legs towards the sky whilst keeping them straight to target the abdominal muscles.

What Muscles do Lying Leg Raises Work

Lying leg raises has compound mechanics which means that many muscle groups are simultaneously working to achieve a single movement. The primary muscles worked are the rectus abdominis, obliques, and hip flexors. The secondary muscles worked are the quadriceps, hamstrings, and erector spinae (lower back muscle).

What Level is the Lying Leg Raises

Lying leg raises are for all fitness levels, from beginners to intermediate, and advanced levels. They are easy to perform if you have basic core strength and decent hamstring flexibility. However, if you find them tough, you can regress to an easier variation such as the lying knee raises. Simply, draw your knees in towards your chest rather than keeping your legs straight because this will reduce the load on your core muscles.

How to do Lying Leg Raises

  1. Lie On Your Back

Begin by lying on your back on the ground with your legs extended and feet are together. Your arms are by your sides with your palms pressed into the floor. Keep your toes pointed at all times. You can use a yoga mat, a carpet, or any soft floor for support and comfort. 

Engage your core and glutes to press your lower back flat into the ground. Your lower back should not be arching. But, if it is, you can place your palms underneath your but or a towel underneath your lower back to prevent arching and lower back pains. This is your starting position.

  1. Press Your Lower Back Flat Into The Ground 

Engage your core and glutes to press your lower back flat into the ground to prevent arching. If you are unable to keep your lower back flat or are experiencing pain there, you can prevent this by placing your palms underneath your butt or placing a towel below your lower back. 

  1. Raise Your Legs Up Towards The Sky

Keeping your legs straight and toes pointed, inhale then exhale as you raise your legs all the way up towards the sky until your butt lifts off the floor. Your legs and torso should be at a 90 degrees angle. Make sure to engage your abs to push your lower back into the ground as there should not be any gap between them. This will help you to target the abdominals while protecting your spine. 

  1. Slowly Lower Your Legs Back Down

Inhale and lower them down until your legs are two to three inches off the ground. You should aim to reach as low as you can without touching the ground. Don’t let gravity control you! The most important thing is your breathing technique: exhale when you raise and inhale when you lower. This will enable you to do more reps with less effort.

Leg Lift Workout

The reps and sets range would vary depending on your fitness level. Combining three to four sets of lying leg raises with 10 to 20 reps each is how to build and sculpt your abs. Better yet, if you combine this with cardio and strength training, you’ll see more gains in your midsection than you could ever imagine. See below for a recommended working reps and sets range:

  • Beginner’s level: 8-10 reps x 4 sets
  • Intermediate level: 10-20 reps x 4 sets
  • Advanced level: 20+ reps x 4 sets
