Kettlebell swings are a full-body exercise that targets muscles in both the upper and lower body, as well as the core. The primary muscles worked during kettlebell swings are the glutes, hamstrings, and erector spinae. Other muscles worked include:

• Calves
• Trapezius (traps)
• Rhomboids
• Abdominals
• Quadriceps
• Anterior deltoids
• Pectorals
• Forearm muscles

Kettlebell swings are particularly effective at targeting the posterior chain, which includes the upper and lower back, glutes, and hamstrings. They can also help improve grip strength. Different variations of kettlebell swings can be used to target specific muscle groups more and address individual weaknesses. Overall, kettlebell swings are a great exercise for improving strength, muscle mass, balance, flexibility, and physical endurance.
