I'm into an extended HST cycle doing the madcow 5x5 routine. Due to circumstances beyond my control I missed w/o 1 & 2 of week 6. I was going to repeat w/o 3 of week 5 and then go into week 6, but changed my mind and did w/o 3 of week 6 even though I missed the 1st 2 w/o's. To my surprise I felt very strong and met all my goals on the squat and RDL's (I'm not doing any upper body moves except light rotator cuff exercises at the moment). Not only did I meet my goals I felt stronger then ever and could have done more than I did. I thought I would be weaker. So here are the big questions - do strength gains come in spurts as opposed to gradual increases or did missing the 2 workouts allow me to recuperate and gain stength? Any thoughts on this?
