snowshoeing is a wonderful way, well maybe not wonderful :D, how about effective, way to stay/get in shape; in addition to the aerobic benefits- it does a great job of working your core, entire legs/glutes and really smokes your hip flexors and abductors. It also does a decent job with your upper body with the poles.

it’s the reason I try and maximize my snowshoe miles prior to the Bob Marshall Open- it is the best way I’ve found to mimic best the rigors of that event
