End of Week 6 overall.  Week 3 doing this Legs routine.  Added in some Kettle Bell swings and some planks and side planks cause I was feeling strong.   Felt real strong.  Maybe it was the extra carbs in yesterdays diet.  

20 Min HIIT; Strength Intervals; Level 6
Legs:  2 x circuits of db squats, db lunges, db setups, db calf raises
Extra:  Kettle Bell swings (50 and 20); plank and side planks
2 x 10 Min HIIT; Speed Intervals; Level 8

Thinking of mixing things up some for the next 3 week segment.
