Yes, fitnessblenders is well known, best of the best. And Ms. Kelly is my favourite girl, wish I can sync with her in workout routines. Tried many times to match, but very hard to go beyond 10 minutes of any video. I have most of their videos on my laptop, downloaded. These are great resources for any one , anytime. These videos helped me in reducing my weight; but I now moved onto more of muscle group specific routines.
I have not seen this particular link, I know about youtube only. Thanks for providing me the link though; yes we can select and search. Jillian Michaels is the next one, if you want to explore. I am now having fresh thoughts after seeing your post. May be I can use one of these videos for morning session, that I want to start. Just do for 15 mins, take shower and go to office.
