It’s not planks or sit-ups — the starburst plank is torture on your abs, obliques and shoulders (so I tried it, and here’s my verdict)

I don’t mind planks, but one of my problems with a standard plank is that the obliques don’t get hit hard enough for my liking. This side plank alternative is torture on your obliques, shoulders, and abs, and comes with a side of balance work.

Forget sit-ups, Russian twists, or boring old crunches, because we’re about to heat things up with the starburst plank instead, and it’s a core-torcher worthy of melting even the strongest midsections.

Here’s what I’ve learned from practicing it

Practicing any kind of side plank (see above a kettlebell side plank) is challenging for me, especially because it requires stabilization of the shoulder and balancing on one arm, and I have an unstable rotator cuff muscle on my left side.

If you’re unfamiliar with the rotator cuff, it’s a group of muscles that support your shoulder blades and stabilize the shoulders. This variation always gets me wobbling and shaking, regardless of how much I practice it.

I opted for 30 seconds per side and 3 rounds, which was plenty enough for me, but you could opt for more rounds or more or less time. I added it to my Pilates and yoga routine, and focused on engaging my waist. It’s a great way to challenge your endurance and balance by loading one side of the body at a time, aiding stability in a static position known as an isometric contraction. If you are new to the exercise, gaze down at your mat for extra balance.

I’m quite used to planking, so I opted to hover my leg away from the mat on both sides, which increased the chore on those little stabilizer muscles around my body to keep me upright rather than crashing to the floor.

Your hip flexors work to help you raise and hold your leg in the air, so this is a great way to increase hip activation if you’d like an extra challenge. Adding the leg lift tests hamstring flexibility and hip strength, so give it a try, but don’t force it.

I found that after a week of adding starburst planks into my routine, my left shoulder was achy. Just remember that while this was a little challenge for me, you don’t need to plank every day to feel and see the benefits, and that goes for all exercise. Take rest when you need it, and experiment with a frequency that works for you.

Moreover, manage expectations around body composition — muscle definition comes from low body fat percentage and muscle growth, so while planks and their many variations can strengthen your body, this won’t guarantee you a six-pack. What planks will do is target superficial and deeper internal muscle groups responsible for posture and stabilization, so they’re well worth doing regardless.
