Let’s be honest. Most of us don’t start thinking seriously about our physical health until something goes wrong – a dodgy knee, a breathless dash for the train, or a moment of realisation that the shopping bags feel heavier than they used to. If you’re in your 40s, 50s, or beyond, this newsletter is for you. And the good news? It’s not too late. Not even close.

When most people think about “getting stronger,” they picture bicep curls or heaving barbells overhead. But strength training is actually three distinct things, and you need all three if you want to move, feel, and live well as the years tick by. Let’s break them down.

Strength: the foundation

Strength, in its purest sense, is your body’s ability to produce force: to lift, push, pull, and carry. From your 30s onwards, we naturally begin to lose muscle mass in a process called sarcopenia. Left unchecked, this can amount to a loss of 3 to 8% of muscle mass per decade, accelerating sharply after 60. The result? Reduced independence, a higher risk of falls, and a body that simply doesn’t do what you ask of it.

The remedy is refreshingly straightforward: resistance training. Squats, deadlifts, rows, pressing movements — exercises that place meaningful load on your muscles. You don’t need to become a powerlifter. You just need to challenge your body consistently. Two to three sessions a week can make a remarkable difference, helping you hold on to the muscle you have and, with time, build more.

Power: the forgotten factor

Power is strength applied quickly: the ability to move forcefully and fast. Think of catching yourself when you trip, rising quickly from a chair, or sprinting across the road before the lights change. It’s arguably the most underappreciated facet of fitness for older adults, and it declines even faster than raw strength.

Research has shown that power output in older adults is a stronger predictor of functional ability, and even mortality, than strength alone. The good news is that it responds well to training. Exercises like medicine ball throws, jump squats (even a gentle hop will do to start), or simply performing resistance exercises with intention and speed can help maintain and restore it. The key word is intent: move with purpose, not just patience.

Muscular endurance: the long game

Muscular endurance is your muscles’ ability to sustain repeated effort over time: carrying the grandchildren around the garden, walking uphill without your legs giving up, or standing through a long afternoon on your feet. It’s the quality that keeps you going, day in and day out.

Building muscular endurance doesn’t require marathon training sessions. Higher-repetition resistance work, bodyweight circuits, swimming, cycling, or brisk walking all contribute. The goal is to train your muscles to resist fatigue, so that the demands of everyday life feel manageable, not like a battle.

Why you need all three

It’s tempting to focus on just one, perhaps a long Sunday walk for endurance, or a bit of lifting for strength, and call it done. But the three facets are complementary, not interchangeable. Strength without power is slow to deploy. Power without endurance fades quickly. Endurance without strength leaves you fragile.

Together, they underpin what physiologists call functional fitness: the capacity to live your life fully and independently. That means climbing stairs without dread, travelling without exhaustion, playing with your grandchildren without sitting it out, and facing your 60s, 70s, and 80s with genuine confidence rather than quiet anxiety.

As the old saying goes, the best time to start was twenty years ago. The second-best time is now. Your future self will thank you for it.

If you’re new to structured exercise, start small and build gradually. A qualified personal trainer, ideally one with experience working with older adults (that’s me!), can be worth their weight in gold. Even two 30-minute sessions a week, done consistently, can transform how you feel and function within a few months. Click the gold button below to get a chat in the diary.
