Today I did Bootcamp and I wondered if it would be OK if I went ahead and did IMAX 2 tomorrow. I wanted some advice because BC really gets my heart rate way up there during the cardio portions of the cycle and then it goes back down during the weight portions, so is it a little like intervals, even though its a circuit workout? I wondered if it would be too taxing on the heart if I went ahead and did an IMAX after that. What are you opinions, educated crowd?
