How To Do

Lie on your side with legs stacked and your lower forearm directly under your shoulder. Engage your core and lift your hips to form a straight line from head to feet, keeping your body rigid and avoiding hip sag. Hold the position, then switch sides.

Step-by-Step Instructions

  1. Begin by lying on your side on the floor or an exercise mat. Stack your legs on top of each other, keeping them straight.
  2. Place your lower arm directly under your shoulder, with your forearm perpendicular to your body and your palm flat on the ground.
  3. Engage your core muscles and lift your hips off the ground, forming a straight line from your head to your feet. Keep your body rigid and avoid sagging at the hips.
  4. Place your upper hand on your hip or extend it straight up toward the ceiling for balance.
  5. Hold this position for the desired amount of time, maintaining steady breathing and keeping your core tight.
  6. Slowly lower your hips back to the ground to return to the starting position.
  7. Repeat on the opposite side.

Frequently Asked Questions

What muscles does the side plank work?
The side plank primarily targets the obliques, helping to strengthen and sculpt your side core muscles. It also engages the abs, shoulders, glutes, and upper legs, making it a great full-body stability exercise.
Do I need any equipment to perform a side plank?
The side plank is a bodyweight exercise and requires no equipment, making it perfect for home workouts or when traveling. You can use a yoga mat for comfort and wrist support if desired.
Is the side plank suitable for beginners?
Yes, beginners can perform side planks by starting with bent knees instead of straight legs to reduce the intensity. As strength improves, you can progress to the full extended-leg position.
What are common mistakes to avoid when doing a side plank?
A common mistake is letting the hips sag, which reduces core engagement and can strain the lower back. Keep your body in a straight line from head to feet and avoid rolling shoulders forward.
How long should I hold a side plank for best results?
For most people, holding a side plank for 20–45 seconds per side is effective. More advanced individuals may aim for 60 seconds or longer, performing 2–3 sets to build endurance.
Are there safe variations of the side plank for people with wrist or shoulder issues?
Yes, you can perform the side plank with your supporting arm extended and palm down, or rest on your forearm to reduce wrist strain. Another option is to keep the bottom knee on the floor to lessen shoulder load.
What are the benefits of doing side planks regularly?
Side planks improve core stability, enhance balance, and strengthen the muscles around your spine and hips. They also help prevent lower back pain by building oblique and deep core strength.
