150 is the magic number.
Fact: Adults who get 150–300 min/week of moderate cardio + 2+ days of strength see big gains in health, energy, sleep, and mood. (PubMed, www.heart.org) Try 5×30-min walks + 2 lift days this week. And if this is too much, break it into even smaller increments that you know you can handle.
Small steps, big wins. 🗓️💪
