Another technique that will target your obliques is the one that begins here.
Get into the full plank posture to begin.
Extend one of your legs and bring your knee toward the elbow of the opposing leg.
To return to the starting position of the plank, push your leg back. Ensure that your abdominal muscles and glutes remain contracted throughout the entire workout.
You should continue to switch sides for twenty to thirty seconds, or for as long as you are able to keep your form correct. Aim for two to three sets.
Tip: Do all in your power to maintain a neutral position for your spine and pelvis as much as you possibly can.
