Yes, I do this all the time. 30-minute steady state cardio or circuit workout + standing leg work one day, then half a kickboxing workout + floorwork OR leg conditioning drills 48 hours later. I mix and match a lot of the segments in different leg workouts, and my body seems to respond so much better to this kind of confusion than the regular standing leg work/floor work twice a week. I also vary the workouts in such a way that I go heavier than Cathe during one session, then match her weights the next, then go lower the next, alternating these different weighted workouts with my mixed and matched ones. I hope that makes sense.
