Cross-Body Crunch
The elbow-to-knee crunch is an effective bodyweight exercise that works the abdominal muscles, specifically the obliques and rectus abdominis. It can be used as part of any workout routine to target the core and tone the "six-pack" muscles.
This exercise is a great way to engage the core and strengthen the abdominal muscles, without the need for any equipment. To perform the elbow-to-knee crunch, begin by lying on your back with your knees bent and feet flat on the floor. Place your hands behind your head and engage your core. Bring your left elbow to your right knee, then extend your left leg. Then switch sides, bringing your right elbow to your left knee while extending your right leg.
To increase the intensity, you can add a twist, bringing your elbow to the opposite side of your knee. This will activate the oblique muscles and further engage the core. You can also add a pause in the crunch position for an extra static contraction.
The elbow-to-knee crunch is an effective bodyweight exercise that can be used to target the abdominal muscles. It can be performed for time or reps as part of any ab-focused workout. With a few modifications, you can increase the intensity and challenge yourself further.

Step by Step Instructions For Cross-Body Crunch
- Lie flat on your back and bend your knees about 60 degrees.
- Keep your feet flat on the floor and place your hands loosely behind your head. This will be your starting position.
- Now curl up and bring your right elbow and shoulder across your body while bring your left knee in toward your left shoulder at the same time. Reach with your elbow and try to touch your knee. Exhale as you perform this movement. Tip: Try to bring your shoulder up towards your knee rather than just your elbow and remember that the key is to contract the abs as you perform the movement; not just to move the elbow.
- Now go back down to the starting position as you inhale and repeat with the left elbow and the right knee.
- Continue alternating in this manner until all prescribed repetitions are done.
Variation: You can also do all of your repetitions for one side and then switch to the other side.
Warm Up Tips
- Start by lying flat on your back with your knees bent at a 60-degree angle.
- Keep your feet flat on the floor and place your hands loosely behind your head.

Cross-Body Crunch Safety Tips
- Warm up before starting the exercise to prepare your muscles for the movement.
- Ensure that you have a proper form throughout the exercise to avoid any strain or injury.
- Keep your feet flat on the floor and your knees bent at a 60-degree angle to maintain stability.
- Place your hands loosely behind your head, but avoid pulling on your neck or using excessive force.
- Exhale as you perform the movement, focusing on contracting your abs rather than just moving your elbow.
- Avoid jerking or using momentum to perform the exercise. Control the movement and engage your core muscles.
- Inhale as you return to the starting position and repeat the movement on the opposite side.
- Take breaks and rest if you feel any discomfort or pain during the exercise.
- Start with a lower number of repetitions and gradually increase as your core strength improves.
- Listen to your body and modify the exercise if needed to suit your fitness level and abilities.
