Lower-Body Strength Training Over 40 — 5 Moves That Keep You Strong
Lower – Body Strength Training Over 40 – 5 Moves that Keep you Strong
Getting into your 40s doesn’t mean your legs are done. But if they’re not being challenged regularly, they will quietly start to lose the strength and resilience you’ve built up over the years — and most people don’t notice until daily life starts to feel harder than it should.
The good news? It doesn’t take a huge programme to turn this around. A handful of well-chosen movements, done consistently, is enough to keep your legs strong, your joints healthy, and your body doing everything you want it to do.
What the evidence says about strength and ageing
- Muscle loss (sarcopenia) starts earlier than most people think. Research published on PubMed suggests adults can begin losing muscle mass from their 30s, with the rate accelerating through the 40s and 50s — particularly in the lower body, which carries us through every movement of daily life.
- Resistance training directly counters this decline. The UK Chief Medical Officers’ Physical Activity Guidelines recommend muscle-strengthening activity on at least 2 days per week for all adults — and for good reason. Strength training stimulates muscle protein synthesis and slows age-related loss.
- Leg strength predicts long-term independence. Studies consistently link lower-body strength to reduced fall risk, better metabolic health, and greater quality of life as we age. This isn’t about aesthetics — it’s about staying capable.
- You don’t need to train like a 25-year-old. Volume, recovery needs, and joint considerations shift with age. Smart programming matters more than intensity for its own sake.
- It’s never too late to start (or restart). Research shows meaningful strength gains are achievable well into your 50s, 60s, and beyond with consistent resistance training.
5 lower-body movements to prioritise after 40
These are the five movements our coaching team consistently returns to with members in their 40s, 50s, and beyond. They’re also highlighted by strength coach Alain Gonzalez — whose work on training for longevity is worth a read — as foundational for staying resilient long-term.
1. Goblet Squat
Why it works: The goblet squat is one of the most forgiving squat variations for anyone with tight hips or a history of lower back niggles. Holding a weight at your chest naturally encourages an upright torso and teaches good squat mechanics — which makes it a brilliant starting point regardless of your training background.
How to do it: Hold a dumbbell or kettlebell at chest height, feet shoulder-width apart, toes slightly turned out. Sit your hips down and back, keeping your chest tall. Drive through your heels to stand. Aim for 3 sets of 10–12 reps.
2. Romanian Deadlift (RDL)
Why it works: The RDL targets your hamstrings and glutes — two muscle groups that are chronically underworked in most people who sit for long periods. Strong hamstrings also protect your knees, which makes this doubly useful as you get older.
How to do it: Hold dumbbells or a barbell in front of your thighs. Hinge at the hips, pushing them back as you lower the weight down your legs. Feel the stretch in your hamstrings, then drive your hips forward to return to standing. Keep a neutral spine throughout. Aim for 3 sets of 8–10 reps.
3. Step-Up
Why it works: Unilateral (single-leg) training is essential over 40. It corrects strength imbalances between legs, reduces injury risk, and directly mirrors real-life movements — stairs, kerbs, hills. It also loads each leg independently without the spinal load of heavy bilateral lifts.
How to do it: Stand facing a bench or sturdy box. Step one foot up, drive through that heel to lift your body, bring the other foot up, then step back down under control. Add dumbbells as you progress. Aim for 3 sets of 10 per leg.
4. Hip Thrust
Why it works: Few exercises target the glutes as directly as the hip thrust. Strong glutes support your lower back, improve your posture, and power almost every movement you do — walking, running, climbing stairs. For anyone who sits a lot, this is non-negotiable.
How to do it: Sit with your upper back against a bench, feet flat on the floor, a barbell or dumbbell across your hips. Drive your hips up until your body forms a straight line from knees to shoulders. Squeeze at the top, lower under control. Aim for 3 sets of 10–12 reps.
5. Leg Press (or Hack Squat)
Why it works: The leg press allows significant quad and glute loading with less technical demand than a barbell squat — making it ideal if heavy squatting doesn’t suit your hips or knees at this stage. It’s not a shortcut; it’s a smart tool. Progressive overload on the leg press produces real, meaningful strength gains.
How to do it: Sit in the leg press machine, feet shoulder-width apart on the platform. Lower the weight until your knees reach roughly 90 degrees, then press back through your heels. Don’t lock your knees at the top. Aim for 3 sets of 10–12 reps.
How to fit this into your week
You don’t need to do all five in one session. Here’s a simple way to structure it:
Option A — Two sessions per week (recommended starting point)
- Session 1: Goblet Squat, Romanian Deadlift, Hip Thrust
- Session 2: Step-Up, Leg Press, Romanian Deadlift (lighter, higher rep)
Option B — One session per week (minimum effective dose)
Pick three of the five movements. Rotate which three you use each week to hit everything over a fortnight.
Leave at least 48 hours between lower-body sessions. Your legs need time to recover — that’s where the adaptation actually happens.
Frequently asked questions
Q: I have bad knees — are these movements still suitable for me? Most of these movements can be modified to reduce knee stress. The RDL and hip thrust in particular place minimal load through the knee joint. We’d always recommend a coaching consultation before starting if you have an existing knee condition — our team can map out what works for your body specifically.
Q: How heavy should I go? Start lighter than you think you need to. The goal in the first few weeks is learning the movement patterns, not maxing out. A good rule of thumb: the last two reps of each set should feel genuinely challenging, but your form should stay solid throughout.
Q: How long before I notice a difference? Most people notice improved stability and day-to-day ease within 4–6 weeks of consistent training. Visible strength changes typically show up around the 8–12 week mark. Consistency matters far more than intensity in the early stages.
