I just did Circuit Blast today for the 1st time. I actually find DM to be harder. Maybe just bc DM is longer? I don't know. Circuit Blast was one of the easier Shock Cardios for me. The med ball pushups were no walk in the park, though. CCC was much harder, and doesn't use weights, while CB does. Maybe if CB was longer.......dunno. Good workout though, I think if you like DM, you'll like CB
