Today's the day where I've done this routine daily for 4 weeks! I set out to do this with the idea that I'd like to do it every day for 8 weeks, and unless something happens, it looks like I will be hitting that goal. Here are some notes from watching this video 21+ times:
- I identified with James' struggles extra hard in the first two weeks. Now I find their chemistry endearing
- I'm still sad that there wasn't a consistent countdown to begin each exercise to make sure that I would utilize all of the allotted time for each exercise
- The dialogue has become a reward-trigger for me. When Helen brings up the glass analogy in round 3 of side plank (my least favorite move of the routine) I know that I will make it through
- After three weeks (from sedentary lifestyle) I was able to do this routine twice in a row. To avoid exhaustion, I now do a 30 minute routine twice a week. Starting next week I will increase that to three times a week
- Poor James.
Thank you so much to GCN and GTN for this great HIIT exercise routine! It's been a blast doing it.

Awesome routinee!!! I'm doing it every morning. Thank you, guys!! Would be nice to have a ring sound everytime the count starts and finishes for each repetition, so we don't have to come back to the screen to confirm when we start and when we finish. :)

Did this today, 3 hours later sore like crazy, for sure this works. Out of shape a bit but 15 minutes get you this sore, I’m a fan. Thanks

Massive HIIT! All sweaty in 15 min, like been on it for a whole day💪🏾👍🏿

[bugzbunnyTvShow]

To be honest, that was pretty easy for me, but still broke a sweat out of me so, it was worth it! Ty guys for the inspiration and the motivation!!

[Asiagirl]

I did this as warm-up for my muscle training and I‘m drenched in sweat now.. and sneezing. Well time to continue! I think I will do this before every Training now.

[chadtravnick]

great workouts! I find it very amazing that female and male does the workout differently but similar. I am trying to find a workout that benefits both.
