## Summary

Looking across dozens of trials in frail and pre-frail people over 60, regular cardio improved frailty scores, mood, leg strength, quality of life and thinking skills. The type didn't seem to matter much. Tai Chi, dance and plain walking all worked. Researchers couldn't pin down an ideal amount, but starting with modest, doable volumes looked sensible.

## Practical Takeaway

This review suggests that for frail older adults, the enjoyable type of cardio may matter more than the amount.
