Kettlebells are great for tightening your body. They add a new dynamic to a workout that regular weights cannot achieve. In this move, you'll really work your arms, for a nice toned look.
Step 1: Hold the kettlebell between your legs, which should be shoulder-width apart.
Step 2: Swing your arms up forcefully in front of you.
Step 3: Continue to bring your arms above your head in one motion, keeping your focus on your core and lower body, not arms.
Step 4: Let the kettlebell fall back between your legs and repeat.
