Professional skiers are known for having nice butts. In order to ski hard and handle rough terrain skiers need a strong posterior chain. This includes glutes, hamstrings, and lower back muscles.
A great exercise that includes the core and posterior chain is a lunge with the front foot on a bosu ball. Try this exercise to challenge yourself and get your body ready to hit the hills.
