Two months of stairs and power workouts to prepare for the winter snowboarding and backcountry snowmobiling in the mountains.
Need the strong upper body, shoulders and arms for the snowmobiling. Also use plyometrics for explosive leg strength for snowboarding and snowshoeing. Most of all need strength and flexibility in my mid-trunk section, lower back and abs, for carring my pack and wrestling the mountain sled in the powder.
