A few Carolines a week is more than enough. The past month I averaged three because I'm trying to get back into cardio and like Fibrous my yoga has fallen off a lot, so need to get back to that, too.
At the moment her upper body routines are more appealing to me than lower. This week I did both Intent Day 2 and Day 4 (but there too many lateral raises and rear delt flyes and general repetition between the days; in the future I would only do one) and a great PE quads one recommended by Sam.
Then for glutes I did my own thing- in addition to the Dan Johns kettlebell challenge, I did 4 sets of barbell RDL @65kg and also a "fun" Move with Nicole bodyweight barre routine that keeps my hips and knees mobile and works the muscles a bit without any kind of fatigue.
No hip thrusts or glute bridges this week. :D Giving my perpetually tender hips a rest.
I have done 15 out of 45 Play Days and will maybe repeat these ones: day 4, day 5, day 9, day 11, day 40. Maybe 15 (pyramid) for fun. It's been an interesting programme to log in and look at, but for me really, really hit and miss. I have never completed any of Caroline's programmes fully because I refuse to do shoulders-only days, EMOMs and anything with sissy squats. And those atrocious day 5 "light" circuit days from MAX prevented me from completing what was otherwise for me a fantastic programme.
@Fibrous , I challenge you to do this one! 15 mins and it covers a lot of bases. It'll make you feel better.:)
