In my opinion, kettlebell swing is one of the greatest exercises ever invented. It's very functional and has a lot of carryover to almost any activity and it will improve performance in any sport...I would argue that swings are a better posterior chain/hamstrings exercise than deadlifts. A 53 pound kettlebell swing done correctly can generate as much force as a 400 pound deadlift. Deadlifts are hard to recover from and strain your CNS too much if done too often....Kettlebell swings are a lot easier to recover from and can be done more frequently.
