The first 90 days after 50: where to start
Most restarts don't fail on willpower. They fail because too much changes at once.

If you've spent years working at a desk and now want to make a change, it helps to take things gradually in the first few weeks. Early enthusiasm can make it easy to take on too many new habits at once.
What can help when new habits become harder to keep after a few weeks?
A new way of eating, a new training plan, an earlier bedtime and less alcohol add up to more decisions than a busy week can carry. When a hard stretch arrives, it isn't one habit that goes – it's the whole system.
- Too many changes started together.
- Weekly targets set too high.
- No plan decided in advance for what happens after a missed day.
- Success measured as perfection rather than continuation.
A more realistic 90-day split
- Days 1–30: sleep rhythm and a daily walk. Nothing else.
- Days 31–60: two simple strength sessions a week, and protein at main meals.
- Days 61–90: rehearse the hard situations – travel, family meals, coming back after illness.
