Didn't notice it with RTTC, but with S & L I had a slight lower back soreness the first time I did it, but not after that. My neck was not sore the day after, but it definitely felt like it was getting its own workout during the workout! By the time I got to the abs I was putting my hands behind my neck for most movements rather than holding my hands out in front. I really felt like I was straining my neck during those endless overhead triceps things and during the endless shoulder work. I guess I should scale back on the weight for those rather than risk straining my neck. I was using 10s for both of those segments, maybe I'll go down to 8s. But the weird part is, I felt like my triceps and shoulders were not getting that tired, just my neck was getting tired! Gotta check my form.
I love the 2 new Jari workouts though. I'm doing just a Jari rotation for a few weeks, a little scary after years of Cathe heavy heavy weight workouts! But I actually think after only 2 weeks I look a little longer and leaner. And BOY did I have DOMS the first time I did S&L, like for 3 days afterwards. It's obviously very effective. And I like it that the workouts feel easier to me while I"m doing them, during Cathe's workouts (even the weight workouts) I always feel like I'm putting out great effort, and with Jari I feel more like I'm just going along at a relatively sane pace. It's a nice change.
