Today I did Jillian Michaels' Shred it with Weights workout, which uses Kettle Bells. I don't have Kettle Bells and JM says that you can use a dumbbell from three-eight pounds. I have ten pound dumbbells and four one-pound weights so I hooked my one-pound weights together and used them mostly, although sometimes the ten pound dumbbell and it was fine.
It's similar to the Shred, you do a warm up, a cool down and three circuits in between. It didn't seem too hard so maybe I should use more weight. In the third circuit, it got pretty challenging for me but that could be because by then I was really doing it for several minutes in a row. I was messing around with Anthony in the first circuit and had to keep pausing it.
I enjoyed it, I'd do it again. It makes me want to get a Kettle Bell and see if it makes a difference.
