Side Plank for Women Over 40
Side plank guide for women 40+. Strengthen your obliques, protect your spine, and improve lateral stability during perimenopause.

The short answer
How do you do a side plank? Stack your feet and place your forearm on the floor with your elbow directly under your shoulder. Press into your forearm and the side of your bottom foot to lift your hips off the floor. Your body should form a straight line from head to feet.
Why this matters in midlife
The side plank is the most effective exercise for the quadratus lumborum — the deep lateral stabilizer that prevents the pelvis from dropping during single-leg activities like walking and climbing stairs. In perimenopause, hip abductor weakness and gluteus medius atrophy cause a lateral pelvic tilt that leads to hip, knee, and lower back pain. The side plank addresses this entire lateral chain in one movement while also loading the spine laterally, which builds bone density in the vertebral bodies from a different angle than front-loaded exercises.
How to do a side plank: step by step
Lie on your side
Stack your feet and place your forearm on the floor with your elbow directly under your shoulder.
Lift your hips
Press into your forearm and the side of your bottom foot to lift your hips off the floor. Your body should form a straight line from head to feet.
Stack and brace
Top hand can rest on your hip or reach toward the ceiling. Squeeze your glutes and obliques to maintain the line.
Hold and breathe
Hold for your target time while breathing steadily. Do not let your hips sag or rotate forward.
Common mistakes
- Hips sagging toward the floor — weak obliques and glute medius; start with a knee-down variation.
- Hips rotating forward — your body should be in one plane; imagine your back is against a wall.
- Elbow too far forward — the elbow should be directly under the shoulder to avoid rotator cuff strain.
Modifications
Easier
Bend your bottom knee and rest it on the floor (knee-down side plank). This shortens the lever and reduces the load.
Harder
Lift your top leg (star side plank), add hip dips, or hold a dumbbell in your top hand for external load.

Common questions about the side plank for women over 40.
Aim for 3-4 sets of 15-20 seconds per side with perfect alignment. A 15-second side plank with a straight body is more valuable than a 60-second hold with sagging hips. Build to 30-45 seconds over several weeks.
Almost everyone has a weaker side — usually the non-dominant side. This asymmetry increases after 40. Always start with your weaker side and match the stronger side to the same volume. The gap will close over 4-8 weeks.
Yes. Side planks strengthen the gluteus medius and quadratus lumborum, which are the primary stabilizers of the pelvis. Weakness in these muscles is one of the most common causes of lateral hip pain (greater trochanteric pain syndrome) in women over 40.
Key takeaways
- The side plank is a intermediate-level exercise that requires no equipment.
- The side plank is the most effective exercise for the quadratus lumborum — the deep lateral stabilizer that prevents the pelvis from dropping during single-leg activities like walking and climbing stairs.
- Avoid the top mistakes: hips sagging toward the floor.
- Pair with Plank for a complete training block.
