Difficulty level: Intermediate
Target Muscle: Abdominals
Equipment: Bodyweight
Instructions for proper form
Start in a forearm plank position with your elbows directly under your shoulders and your body in a straight line from head to heels. Engage your core to maintain a neutral spine. Slowly bring one knee towards the elbow on the same side, while keeping your hips stable. Return to the plank position and alternate with the other knee. Ensure your hips do not sag or rise during the movement and keep breathing steadily throughout.
Common mistakes to avoid
Avoid letting your hips dip too low or rise too high, as this can strain your lower back. Do not rush the movement; maintain control to prevent injury. Failing to keep your core engaged can also lead to improper form and reduced effectiveness.
Benefits
Specific benefits of the exercise
This exercise strengthens the abdominal muscles, particularly the rectus abdominis, enhances core stability, improves balance and coordination, and enhances functional strength.

Who this exercise is best for
This exercise is best for individuals looking to enhance their core strength, athletes seeking improved stabilization, and those who perform activities requiring balance and coordination.
Scientific studies supporting its effectiveness
Studies, such as one published in the Journal of Strength and Conditioning Research, indicate that exercises targeting core stability significantly improve athletic performance and overall functional strength. Additionally, core stability has been associated with reduced risk of injury in physically demanding sports.
Variations
Beginner modifications
Knee Plank: Hold a modified plank position with knees on the ground to ease the load. Alternatively, perform the movement without alternating the knees, focusing on holding the plank.
Advanced progressions
Plank with Knee to Opposite Elbow: Reach your knee towards the opposite elbow for added difficulty. You can also add a push-up after each knee tuck for an extra challenge.
