The phase for hitting the maximum heart rate during intervals continues...
Saturday: 6 reps of 4 minutes on; 4 minutes off
Sunday: Maintenance Weight Lifting and Core Workout
Monday: 12 reps of 2 minutes on; 2 minutes off
Tuesday: 24 reps of 1 minute on; 1 minute off
Edit: I just finished my 24 reps of 1 on; 1 off and did them outside as hill climbs. My goose is totally cooked. Why I threw that weight lifting day in the mix at that spot remains a mystery to me (actually, it was the only day I could get to the gym this week). I won't be doing that again!
My upcoming two days off have now been dutifully earned.
