Two-Arm Kettlebell Swing
Works: Hamstrings, glutes, abs and shoulders
Keeping your feet hip-width apart, arms at your sides, and the kettlebell in both hands, stand tall.
You should your knees and bring the kettlebell down between your thighs.
Quickly straighten your legs and bring your arms forward to eye level to exit the squat. At the peak of this exercise, the kettlebell should float freely in the air.
Just keep going like that for a whole minute. (You can do this arm exercise for a minute, or you can do 8-12 repetitions.)
