As the name suggests, the dumbbell skier takes the motion of skiing and replaces the poles with dumbbells. The hip and torso motion are similar to a kettlebell swing, as are the muscles it targets, including the hamstrings, glutes, upper back, and grip. However, unlike the traditional kettlebell swing, the arms are outside of the knees. This movement can be performed for time or for reps, but is usually performed for relatively high reps, such as 8-12 sets per rep or more, as part of a fat-loss or athleticism-focused circuit or workout.
