Stop Doing Crunches: Try Side Planks for Core Strength After 50

By Lily Reed · August 12, 2026

Building core strength is crucial at any age, but especially as we get older. For men over 50, traditional core exercises like crunches may not provide the support your body needs. Instead, consider incorporating side planks into your fitness routine. This Pilates move emphasizes functional core strength, improves balance, and might just be the secret to moving better through daily life.

Why Choose Side Planks?

Side planks are often overlooked, yet they offer numerous benefits compared to traditional exercises. Here’s why they deserve a spot in your workout:

  • Functional Core Strength: Side planks engage the obliques and deep core muscles, enhancing strength that supports daily movements, like getting up from a chair or tackling stairs.
  • Spine Support: A strong core stabilizes your spine, which is particularly important for men dealing with back pain or stability issues.
  • Balance Improvement: As we age, maintaining balance becomes essential to prevent falls. Side planks challenge your balance, helping to keep you steady on your feet.

Getting Started with Side Planks

To perform a side plank correctly, follow these basic form cues:

  1. Start Position: Lie on your side with your legs stacked, one foot resting on top of the other. Your elbow should be directly under your shoulder.
  2. Lift Your Hips: Engage your core and lift your hips off the ground, forming a straight line from head to feet. Avoid letting your hips sink.
  3. Hold and Breathe: Maintain this position, ensuring your shoulder is away from your ear and your neck is relaxed. Breathe steadily and focus on keeping your body aligned.

Common Mistakes to Avoid

  • Letting the Hips Drop: Keep your body in a straight line; avoid sagging in the middle.
  • Incorrect Elbow Position: Your elbow should be under your shoulder for optimal support.
  • Holding Your Breath: Remember to breathe steadily to maintain stability and focus.

Progressions and Modifications

If you’re new to side planks or have back discomfort, start with beginner modifications:

  1. Knee Side Plank: Instead of balancing on your feet, drop your bottom knee to the ground while keeping your upper body lifted.
  2. Wall Side Plank: Stand with your back against a wall and perform the side plank using the wall for support. As you gain confidence, you can transition to floor-side planks.

A Simple 4-Week Progression Plan

To effectively integrate side planks into your routine, try this 4-week plan:

  • Week 1: Start with 10-15 seconds on each side, holding the basic side plank or a modified version. Aim for 3 sets.
  • Week 2: Increase your hold time to 20-30 seconds. Continue with the modified version as needed.
  • Week 3: Pull your feet together for standard side planks, aiming for 30-45 seconds. Incorporate 4 sets.
  • Week 4: Advance to holding the plank for 45-60 seconds. Challenge yourself with variations like leg lifts or arm raises while in the plank position.

Tips for Lasting Results

  1. Consistency is Key: Aim to incorporate side planks 2-3 times per week.
  2. Listen to Your Body: Feel free to adjust the exercises to match your fitness level and comfort.
  3. Combine with Other Exercises: For well-rounded core strength, mix side planks with exercises that work the front, back, and deeper muscles of the core.

By shifting your focus from crunches to side planks, you'll not only enhance your core strength but also improve balance and mobility for everyday tasks. Remember, it's about training your body to move better in real life, and side planks are a fantastic way to achieve that. Make the change today and see the benefits for years to come!
