I went to the Gym for the first time in over a month yesterday (I think I have only been once since starting 5:2 and that was at the start). I did 15-20 minutes on each of the Exercise bike and Stepper, then 20-25 minutes on each of the cross trainer and treadmill. Between each of the cardio workouts I did one or two upper torso weight machines for arms. The aim was to "take things easy" and I lowered the levels on several of the cardio machines. Having lost a half stone or so since the last visit, it all felt much more relaxed.
One interesting thing was at the beginning of the session. I like to take my resting pulse after 1 minute on the exercise bike with no pedalling (just sat there getting all Zen and relaxed). The reading was 78. This was the lowest I can remember seeing it! I normally think of a reading <90 as "good" and at times (say if I've dashed to the gym straight after work) it's been much higher (116-120).
So I'm wondering if this is the benefit of "repair mode" (or maybe regular daily walking)?
