A strong core demonstrates stability, balance, and control over your body. At 50, your ability to hold challenging positions says a lot more about your health than how many sit-ups you can crank out. These positions aren’t flashy, but they test deep levels of strength and control that directly connect to how you move in daily life.
Think of your “biological age” as how young your body performs compared to your actual birthday age. If your muscles, joints, and nervous system still respond with the sharpness of someone younger, your biological age is lower. The opposite is also true—struggle with simple stability work, and it can highlight where time has caught up.
By practicing and holding certain positions, you strengthen the deeper muscles that protect your spine, hips, and shoulders. These muscles are the foundation for resiliency and long-term mobility, keeping you moving well and feeling capable as the years go on.
The three positions below aren’t about max effort or breaking records. They’re about proving your core is still youthful and responsive. Mastering these holds at 50 shows your body is functioning at a level that feels decades younger.
4 Core Holds To Prove Your Strength Is Still Youthful at 50
Position #1: 3-Point Plank
The 3-point plank removes one point of contact, instantly forcing your body to resist rotation and collapse. This position tests anti-rotation strength, shoulder stability, and your ability to keep your spine neutral under pressure. Holding this without sagging at your hips or twisting through your torso proves your core is both strong and highly functional.
Muscles Trained: Rectus abdominis, obliques, transverse abdominis, shoulders, glutes
How to Do It:
- Start in a forearm plank with elbows stacked under shoulders.
- Keep your core braced and glutes engaged.
- Lift one arm a few inches off the ground while keeping your hips square.
- Hold the position without shifting or twisting.
- Switch sides after the set.
Recommended Sets and Reps: Perform 3 to 4 holds of 15 to 30 seconds per side. Rest for 30 to 45 seconds between sets.
Best Variations: Side plank hold, plank with alternating reaches, long-lever plank.
Form Tip: Drive your supporting elbow and toes into the floor as if you’re “pulling the ground apart” to stay locked in.
Scoring:
- Beginner: 10 to 15 seconds per side
- Intermediate: 20 to 30 seconds per side
- Advanced: 40 to 60 seconds per side
Position #2: Quadruped Position Hold (Bear Hold)
The bear hold teaches you to brace your core in a neutral spine while supporting your body close to the ground. It’s one of the most effective ways to train stability because you’re fighting to keep your back flat and hips steady while gravity tries to pull you down. If you can own this position at 55, it signals strong, deep core muscles and resilient shoulders.
Muscles Trained: Rectus abdominis, transverse abdominis, obliques, hip flexors, shoulders, quads
How to Do It:
- Begin on hands and knees with wrists under shoulders and knees under hips.
- Tuck your toes and lift your knees 2 inches off the floor.
- Keep your back flat, core braced, and hips level.
- Hold the position without shifting or rounding your spine.
- Breathe steadily while maintaining tension.
Recommended Sets and Reps: Hold for 20 to 40 seconds, 3 to 4 sets. Rest for 30 seconds between holds.
Best Variations: Bear crawl hold with shoulder taps, bear crawl steps, bear hold with opposite limb lifts.
Form Tip: Imagine balancing a glass of water on your lower back—don’t let it spill.
Scoring:
- Beginner: 15 to 20 seconds
- Intermediate: 30 to 40 seconds
- Advanced: 50 to 60+ seconds
Position #3: Split Squat Hold
The split squat hold challenges balance, stability, and lower-body endurance. By holding the bottom position, you force your glutes, quads, and core to stabilize together. This not only strengthens your legs but also trains single-leg stability, a marker of youthfulness and resiliency as you age. Your ability to stay balanced here demonstrates how well your hips and core are working together.
Muscles Trained: Quads, glutes, hamstrings, calves, core
How to Do It:
- Stand with one foot forward and the other back in a split stance.
- Lower into a lunge until your back knee hovers just above the ground.
- Keep your torso upright and core tight.
- Hold the position without wobbling or leaning.
- Switch legs after the set.
Recommended Sets and Reps: Perform 3 to 4 holds of 20 to 30 seconds per side. Rest for 30 to 45 seconds between sets.
Best Variations: Elevated split squat hold (rear foot on a bench), isometric lunge pulses, split squat with overhead reach.
Form Tip: Push your front heel into the floor and squeeze your glute to stay balanced.
Scoring:
- Beginner: 15 to 20 seconds per side
- Intermediate: 30 to 40 seconds per side
- Advanced: 45 to 60 seconds per side

Position #4: Overhead Carry Hold
The overhead carry hold is a powerful test of core stability, shoulder strength, and posture. By locking weight overhead and standing tall, you’re forced to stabilize from your fingertips down to your feet. At 50, being able to control this position signals youthful shoulder health, resilient core muscles, and the ability to stay upright and strong under pressure. It mimics the strength you need for daily tasks, such as carrying groceries or reaching overhead, with control.
Muscles Trained: Shoulders, upper back, core, glutes, grip, quads
How to Do It:
- Stand tall with feet hip-width apart, holding a dumbbell or kettlebell in one hand.
- Press the weight overhead until your arm is fully extended and elbow locked out.
- Keep your ribs pulled down and core tight—avoid arching your lower back.
- Squeeze your glutes and stand tall, eyes forward.
- Hold the position steady, then switch arms after each set.
Recommended Sets and Reps: Perform 3 to 4 holds of 20 to 30 seconds per arm. Rest for 45 seconds between sets.
Best Variations: Double-arm overhead hold, single-arm overhead march, bottoms-up kettlebell hold.
Form Tip: Imagine “pushing the ceiling away” while pulling your ribs down toward your hips to keep a rock-solid posture.
Scoring:
- Beginner: 15 to 20 seconds per arm
- Intermediate: 25 to 35 seconds per arm
- Advanced: 40 to 60 seconds per arm

Lowering your biological age may not be the challenge you once thought it was. If you’re training your body to move, recover, and function at its best, no matter your actual birthday, you’re on the right path. Each of these positions helps, but the real secret is creating consistency across your training, lifestyle, and recovery habits. The following strategies are proven ways to turn back your biological clock:
- Train Core Stability Regularly: Add planks, bear holds, and split squat holds to your weekly routine. Even 10 minutes, 3 times per week, makes a big difference.
- Lift Weights for Strength and Muscle: Resistance training helps preserve lean mass and bone density, two key markers of youthfulness.
- Prioritize Mobility Work: Daily mobility flows and stretches help keep joints supple and improve your movement in core positions.
- Walk More Every Day: 8,000 to 12,000 steps daily, improves cardiovascular health, fat metabolism, and recovery.
- Eat for Longevity: Focus on lean protein, whole foods, and anti-inflammatory foods like fish, nuts, and vegetables.
- Prioritize Sleep and Recovery: Deep, consistent sleep is one of the strongest predictors of lower biological age.
- Manage Stress: Breathing drills, meditation, or simply time outdoors can help reduce the wear-and-tear effect stress has on your body.
