Hi T,
MIC is a 70 minute, very advanced cardio workout. The first half is hi/lo floor aerobics and the second half is a step workout with an intensity blast at the end. Depending on what you have, you could do something like the following:
Option 1:
Either program your dvd player or use the Mix 'n Match feature:
Step Blast warm up;
Step, Jump & Pump hi/lo add-on premix (cardio only, no weights);
Step Blast combo 2;
Step Blast combo 3;
Step Blast challenge, cool-down & stretch.
Option 2:
Circuit Max (skip the weight work) followed by CTX Step & Intervals.
Hope this helps,
Sandra
