I think Allie and I had this conversation before, but we were wondering why Cathe says, after the first drill, "they get harder." Allie and I were of the opinion that the first cardio section is one of the toughest (I think cardio #5 is the toughest) and three and four were the easiet. I used to only do the cardio only premix. But now that I do the workout as-is, I think that Cathe was right in that the circuits as a whole get tougher. This is gonna sound so lame, but I CANNOT do the very last exercise - the pushups into a side plank. I know Cathe and crew are only using 3# weights, but she's essentially doing triceps pushups on her toes, and I cannot do triceps push ups. Triceps pushups are my nemesis!! That said, I love Drill Max!! It's got everything - strength, endurance, functional fitness, cardio, floorwork, seated work, standing work - everything!!
