It's completely understandable why T-Rex doesn't like Swings. With his short arms he's going to have a real hard time getting a good enough Backswing to get the Kettlebell moving with any speed. The best he could hope for is a slow, wimpy Lat Raise!?!?
It's a good thing that you're not T-rex and you can take full advantage of your long arms and legs as well as hips to create a Backswing that make any self-respecting Kettlebell fear you!
