5 Yoga Poses To Slim Your Waist And Tighten Your Core

Rock your crop with confidence.

You know that feeling when you’ve been holding a plank for so long it feels like you’re being punched in the stomach? What makes you hold on? Is it the coveted ab crack? That cute crop you’ve been eyeing off on Net-A-Porter?
While it may make you grit and bear that last 30 seconds, there’s more to our abs than serious definition.
“Our core is the powerhouse and driving force behind the strength our body needs to function and move throughout the day. A strong core not only helps to prevent injuries, and reduce back pain. It also protects our most important internal organs. Engage your core, stand taller and feel confident,” explains Claire Grieve, celebrity yoga instructor and abs ambassador.
Below, she shares her top five yoga poses to strengthen your core and set your abs on fire.

  1. Start on your hands and knees. Place your hands under your shoulders, with your knees directly under your hips. Keep your spine straight and your abdominal muscles tucked in without arching your back.
  2. Lengthen the left leg back and right arm forward simultaneously while maintaining a neutral spine. Your leg is lifted to the hip’s height and arm is lifted to the shoulder level. 
  3. Hold this position for 3 inhales and exhales before coming back to the starting position. Repeat with the right left and left arm.
  4. Repeat this exercise for about 5 times more on both sides.

One-Legged Chaturanga Dandasana

Good ol’ chaturanga—it’s a traditional transitional pose in a Vinyasa yoga flow, but it also happens to be a killer core and arm exercise. 

  1. Begin in your plank position: Pull the core into the spine, look forward, press your palms and knuckles into the ground, while engaging the back muscles to support the spine. Tuck the tailbone and flex the back toes.
  2. Exhale rolling your body forward more onto your tippy toes.
  3. Lower halfway down, keeping your elbows tucked into your sides and one leg lifted.
  4. Hold for a moment and inhale.
  5. Exhale and press back up into starting position and repeat with the other leg.
  6. Repeat with both legs 10 times.

Plank Knee-to-Elbow Variations

“Plank pose is one of the most effective exercises as it not only strengthens the core but also strengthens the wrists, shoulders, chest, buttock, spinal muscles, triceps and neck.” Adding different, challenging variations to plank by throwing off the balance helps to target and engage specific core muscles, like the obliques. 

  1. Begin into a push-up position on your hands and toes; lengthen all the way from the crown of your head to your heels. Keep your core pulled into your spine, back is flat.
  2. Inhale. Lift your right foot off of the ground bend your knee in, engage the core, and draw it toward your right elbow. Connect the knee and elbow hold.
  3. Exhale, extend your right leg back to starting position.
  4. Inhale, lift your right foot off of the ground, take your knee to your left elbow allowing for the core to twist. Connect and hold.
  5. Exhale, extend your right leg back to starting position. Repeat with the left leg.
  6. Repeat 10 times.
