Fitness at every age: How fit should you be in your 20s, 30s, 40s, 50s, 60s and beyond?

Staying active isn’t just about looking good - it’s about keeping your body strong, mobile, and resilient at every stage of life. Regular movement supports muscle strength, balance, bone density, mental wellbeing, and longevity.

Here’s a decade-by-decade guide to realistic fitness benchmarks that can help you measure and maintain your health — plus tips on how to incorporate them into your routine. Remember: everyone starts at a different place, and these are guidelines, not rules.

In Your 20s: Build Your Fitness Foundation

Your 20s are the best time to build strength, stamina, and flexibility. You’re setting the base for your 30s and 40s.

Targets to aim for:

• Run or jog 5km comfortably: Builds cardiovascular health and endurance.

• Touch your toes with straight legs: A sign of good hamstring and lower back flexibility.

• Lift a moderate weight safely (around 15kg): Strength training builds lean muscle and bone density, protecting against osteoporosis later in life.

Why it matters: These early habits establish muscle memory, coordination, and aerobic capacity that will make future fitness easier to maintain.

How to do it: Mix cardio (running, cycling, HIIT) with resistance training (bodyweight moves or light weights) and stretching (yoga or Pilates).

 In Your 30s: Maintain Strength and Balance Flexibility

Your 30s can be busy — careers, children, and responsibilities. This is often when people let fitness slip, but it’s critical to maintain momentum.

Targets to aim for:

• Cycle or do steady cardio for 20 minutes: Supports heart health and endurance.

• 20 continuous push-ups (modified if needed): A measure of upper body and core strength.

• Hold a yoga pose like Downward Dog with heels flat: Keeps hamstrings flexible and spine mobile.

Why it matters: Muscle mass naturally begins to decline in your 30s, so strength training helps preserve it. Flexibility training reduces stiffness from desk jobs or parenting demands.

How to do it: Short, efficient workouts matter here. Try strength circuits, brisk walking with pram/kids, or yoga before bed.

In Your 40s: Prioritise Strength and Stamina

Your 40s are a pivotal decade — hormone changes, slower metabolism, and joint niggles start showing up. Now it’s about protecting your future body.

Targets to aim for:

• 30 minutes of cardio (e.g. tennis, swimming, or football): Keeps your cardiovascular system strong.

• Squat with 20kg weight safely: A marker of lower body strength, critical for bone and joint health.

• Maintain mobility with full toe touches or deep lunges: Helps reduce stiffness and back pain.

Why it matters: Perimenopause often begins in your 40s, making weight training especially important for bone density and metabolism.

How to do it: Prioritise strength training 2–3 times per week, add mobility sessions (yoga, Pilates), and keep active daily with walks or cycling.

In Your 50s: Focus on Core, Balance and Functional Strength

By your 50s, protecting your independence becomes the goal. Balance, stability, and core strength are vital.

Targets to aim for:

• Swim 30 lengths (or 20–30 minutes without stopping): Low impact cardio that’s gentle on joints.

• Hold a 30-second plank: A strong core prevents back pain and supports posture.

• Sit-to-rise test (sit cross-legged on the floor and stand without using your hands): A proven marker of longevity and mobility.

Why it matters: Strong core and balance reduce falls. Swimming and walking are joint-friendly yet effective for heart and lung health.

How to do it: Incorporate functional strength moves (squats, lunges, planks), enjoy low-impact cardio (swimming, brisk walking), and add mindfulness-based fitness like yoga for balance and mental health.

In Your 60s & 70s: Keep Moving, Keep Independent

Movement is medicine in later decades. Even light activity keeps joints lubricated, circulation strong, and confidence high.

Targets to aim for:

• Walk for an hour daily: Builds stamina and keeps weight in check.

• Balance on one leg for 30 seconds: Strong predictor of fall risk and stability.

• Walk heel-to-toe in a straight line (10 metres): Tests balance and coordination.

Why it matters: Falls are one of the biggest health risks at this age. Simple mobility and balance drills can make the difference between independence and frailty.

How to do it: Prioritise walking, gentle resistance training (bands or light weights), tai chi, yoga, or Pilates. These keep muscles strong, prevent stiffness, and maintain balance.
