I'm in week 8 of my return to being semi-serious about fitness. I started out in week 1 doing 4-30 minute workouts a week where I spend 70% of the time in the 70-80% HR zone and 10% of the time in the 80-90% zone. I have worked up to where this week I had planned to use the same zones with 3-50 minute workouts and 1-40 minute workout with the above zones.
Through yesterday, I felt good doing the workouts and had no problem getting into the HR zones I was attempting. Yesterday when I was attempting a 40 minute workout, I simply could not get my HR up to the proper level. I tried for 15 minutes and was just beating myself into oblivion and simply couldn't get into the 70-80% zone no matter how fast I spun and no matter what gear I tried. At that point I said the heck with it and dropped down into the small chain ring and spun the rest of the workout.
Am I in need of a rest/light week? If so, how little should I do? How often should I schedule a rest week in the future?
That is all.
