Whatever works! As long as you're using proper lifting form, and are taking care of your back, what matters is that you're having fun! I'd love to do crossfit. I've done some stuff, but the tire isn't one of them.
Writer, mother, wife, and breadwinner. I love to run, but running doesn't love me, so I'm switching to my low-impact bike.
