Kettlebell swings are a full-body workout 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, spinal erectors, and muscles of the upper back. Other muscles that are activated during kettlebell swings include the quadriceps, abdominals, anterior deltoids, pectorals, and forearm muscles. Kettlebell swings are a high-intensity, low-impact exercise that can improve cardiovascular fitness, strength, and explosive power. They can also burn a lot of calories in a short amount of time and improve grip strength. Kettlebell swings are a great exercise for those looking for a full-body workout that targets multiple muscle groups.
