Anyone doing Rebecca Louise XFit workouts

Hi Friends,
Have any one been doing xfit videos? While searching for some good workout videos I stumbled upon XFit videos by Rebecca Louise. She has videos for different muscle groups.Its short but intense. I have been doing those workouts on and off and can really feel it in my muscles even if I dont repeat the sets. I use a 2Kg dumbbell. Yesterday did a tight butt workout (which is actually for 10minutes and I did only 5minutes) and my muscles are so sore.
The workout contains different squats like, side squats,wide squats and all. Dont remember all names.
Thought will post it here in case any of you find this helpful.She also has a Navy Seal workout which is only cardio and really makes you out of breath.I have been doing JM 30day shred level 1&2 and the navy seal has more or less same cardio as it.But continuous cardio where as JM is mix of all.
