Starting Hypertrophy Phase

I started the hypertropy phase of the Morris strength plan this week. It was pretty tough going, lots of reps... Morris has you do two days back to back, and then take two days off. I felt OK during the day on the second day, but I felt (understandably) worse during the workout. Today is the first rest day. I'm a little sore, but it's not too bad. I should be good to go again on Saturday. I see why he suggests not riding much during this phase. So far, the lifting has been enough to wipe me out.
