# Building muscle after 40

> You can build muscle well into your 40s, 50s and beyond. Age slows recovery and gradually reduces muscle (sarcopenia) and the muscle-building response to protein, so older adults benefit from slightly higher protein (around 1.6–2.2 g/kg), consistent resistance training 2–3 times a week, and more attention to recovery, warm-ups and joint-friendly exercise selection.

Age is not the barrier most people assume. You can build real muscle after 40 — the principles are the same, but a few margins shift and reward a smarter approach.

## What actually changes with age

Three things to plan around:

- **Recovery slows** — you bounce back from hard sessions a little slower.
- **Sarcopenia** — without training, adults lose muscle steadily from around the 4th decade. Resistance training reverses much of this.
- **Anabolic resistance** — muscle becomes a little less responsive to protein and training, so the inputs matter more.

None of these stops you growing. They just mean recovery and nutrition earn more attention.

## How to train

- **Strength train 2–3 times a week**, covering the main movement patterns.
- Apply [progressive overload](/learn/progressive-overload), but leave a rep or two in reserve more often — quality over grinding.
- Warm up thoroughly and choose **joint-friendly variations** where needed.

## Protein matters even more

To overcome anabolic resistance, aim for the **higher end of 1.6–2.2 g/kg**, spread across the day. Calculate your target below.

## Recover like it's part of training

Sleep, stress and rest days aren't optional after 40 — they're where the adaptation happens. Manage them and progress compounds.

This is exactly the kind of individualisation our coaching is built for: the [muscle-growth](/programmes/muscle-growth) and [elite general health](/programmes/general-fitness) programmes scale training and recovery to your age, history and data.

## FAQ

### Can you build muscle after 40?

Yes. Research consistently shows adults in their 40s, 50s, 60s and beyond build muscle and strength with resistance training. Recovery is slower and gains are steadier than at 20, but the process works — and it becomes more important for health with age.

### How much protein do you need to build muscle after 40?

Slightly more than younger adults, because muscle becomes less responsive to protein with age ('anabolic resistance'). Around 1.6–2.2 g per kg of bodyweight per day, spread across meals, is a sensible target for older adults building or preserving muscle.

### Is lifting weights safe over 40?

For most people, yes — and it's protective. Start at an appropriate level, prioritise technique, warm up well and progress gradually. If you have a medical condition or injury history, check with a professional first.
