As a mom, your body goes through a lot each dayโwhether itโs lifting kids, carrying groceries, or keeping up with daily tasks. A strong core is essential to support your body and improve overall strength. The In In Out Out Plank is an excellent exercise that challenges your core, shoulders, and upper body while improving your stability and posture.

In this guide, weโll explain how to do the In In Out Out Plank, why itโs great for moms, and how to incorporate it into your fitness routine.
What is the In In Out Out Plank?
The In In Out Out Plank is a dynamic variation of the traditional forearm plank that adds movement to engage your core and shoulders even more. This exercise is especially effective for improving core stabilityโa critical factor in reducing back pain, improving posture, and strengthening muscles used in everyday activities.
This move challenges not only your abs and obliques, but also strengthens your shoulders and upper back, areas that are crucial for moms who often perform lifting or holding tasks throughout the day. The “in and out” movement of your feet engages the core muscles in a functional way, enhancing your balance and coordination.

Why is the In In Out Out Plank Great for Moms?
As a mom, you may face several physical challenges from carrying your child, pushing a stroller, or simply bending over and reaching for things. The In In Out Out Plank targets the exact muscles that support these movements and more:
1. Strengthens Core Muscles
- A strong core is the foundation for a healthy back, improved posture, and overall stability. The In In Out Out Plank engages your transversus abdominis (the deep core muscles) and obliques, which are key for keeping your midsection stable and supporting your lower back.
2. Enhances Stability and Balance
- This exercise improves stability by forcing you to maintain a straight body line while moving your feet out and in. It trains your core to keep everything stable, similar to the demands of lifting or carrying things throughout your day.
3. Tones Shoulders and Upper Back
- The In In Out Out Plank strengthens the shoulders and upper back, which helps with everyday tasks like holding your baby, carrying heavy bags, or sitting at a desk for extended periods. By stabilizing these muscles, youโll reduce the risk of shoulder and back pain.
4. Functional Movement
- The movement of stepping your feet in and out mimics the shifting motions you make throughout the day. This makes it a functional exercise that improves strength where you need it mostโhelping you feel more stable and strong in your daily life.

How to Perform the In In Out Out Plank with Proper Form
Proper form is crucial to avoid injury and get the most out of the In In Out Out Plank. Hereโs how to perform the exercise correctly:
1. Start in a Forearm Plank Position
- Begin by getting into a forearm plank position with your elbows directly beneath your shoulders. Your body should form a straight line from your head to your heels.
- Engage your core and glutes to prevent your lower back from sagging.
2. Step One Foot Out
- Step your left foot out to the left, moving it as far as you can while keeping your body stable.
- Ensure your hips and shoulders remain squared and that your body stays in a straight line.
3. Step the Other Foot Out
- Next, step your right foot out to the right, again keeping everything stable and controlled.
- This movement engages your obliques as your body works to stay aligned.
4. Step Feet Back to the Center
- Now, step your left foot back to the center, returning to the starting position.
- Then, bring your right foot back to the center.
5. Repeat
- Perform the movement for 10-15 reps, then repeat the exercise leading with the right foot first.
- Aim for 2-3 sets depending on your fitness level.

Common Mistakes to Avoid in the In In Out Out Plank
To get the most out of the In In Out Out Plank, avoid these common mistakes:
1. Letting the Lower Back Sag
- A common mistake in planks is letting the lower back sag, which can cause unnecessary strain on the spine.
- Solution: Engage your core and glutes to keep your body in a straight line from head to heels.
2. Lifting the Hips Too High
- Lifting your hips too high can make the exercise easier and reduce the activation of your core muscles.
- Solution: Keep your body in a straight line, and only move your feet in and out while maintaining a stable plank position.
3. Moving Too Quickly
- Rushing through the movement reduces its effectiveness and can lead to improper form.
- Solution: Focus on controlled movements and proper form, especially while stepping your feet in and out.
4. Not Engaging the Core
- To get the full benefit of this exercise, it’s important to keep your core engaged throughout the movement.
- Solution: Imagine pulling your belly button toward your spine as you perform the plank.
