How long does it take to build muscle?

Building strength requires progressive resistance training two to three times a week, challenging major muscle groups.

Results also depend on consuming adequate calories and protein.

Orienteering: Great exercise and better thinking skills?

The navigation sport orienteering combines map and compass reading with exercise. It’s a fun way to get outside and get some exercise — and it may even help fight cognitive decline.
