A-Jock, I just wanted to thank you for posting your shorter mish-moshes for me. I've done these three so far:
Rhythmic Step warm-up
Rhythmic Step challenge at the end (all of the previous combos done in a string)
Step Blast blast challenge
Step Blast cool down
Boot Camp cardio only premix including warm-up (~17 min?)
SJP hi/lo add-on premix (~18:30 min)
SJP cooldown
10-10-10 warm-up and kickbox (~14 minutes)
KPC high intensity drills (~15 minutes; do start at the "high intensity drills" selection on the Chapter menu)
Boot Camp kickbox premix (~6 minutes {?}
Boot Camp cooldown
...and they were just the ticket, intensity-wise and length-wise, for my current cario needs. I usually do yoga for about 20-30 afterward. I've done the Imax 2 Blast Only Premix (the one that includes recovery periods), but am afraid to try the one from Imax 3 since I find Imax 3 to be pretty much harder than 2. I'll work my way up to your more difficult compilations. Since they're only 30-40 minutes, there's not as much of a dread factor involved as with your other evil mish-moshes, but they still will no doubt improve my cario endurance. Thanks again!
Oh yeah, please tell Fiona that Rocky's found another woman. She looks to be part chipmunk, but we're pretty open-minded about inter-species relationships in my house.
