Snowshoeing: a tough, but fun workout – only available in winter!

Snowshoeing is a major workout, but if you give it a try you will reap serious fitness rewards. Moving through heavy, thick snow creates resistance, which makes this activity a great cardio workout. This area has some nice snowshoe trails that offer varying degrees of difficulty. If you’ve never snowshoed before, start slow and go with a friend. You will soon begin to enjoy the beauty and silence this sport has to offer while reaping the benefits of the sunshine and a great workout!


Have a Snowball Fight!
Do you want to try something outside, but not up for or interested in snowshoeing? How about a good old fashioned snowball fight! This is a fun way to break a sweat in the winter. While this is not the most hardcore outdoor workout ever – the snow is heavy for your feet as you run around dodging snowballs and gives the muscles in your legs a workout. Once again – good old fashioned fun that can only happen in the winter!
