If you don’t have any kettlebells you should get some, right now…. haha, no rush, but seriously I love them. I ordered mine off amazon since with my prime membership shipping was free on such a heavy item.
I use a few different weights, right now a 10lb and a 15lb one, as certain exercises are easier so I use the heavier weight for those. With the ones that are a little more difficult I opt for the lighter weight.
