Just over a month ago I did a 30 day challenge. It consisted of 4 12 minute HIIT exercises (one each day) and then a 5th day of an intense 20-30 minute session.
I found I did not lose much weight on it, but each session has me beat and I am so much stronger now.
I am wondering if this is enough cardio or if I should be adding in 15 minutes of jump rope/high knees/running in place (you get the deal).



for sure... I see that you've done very well in your weightloss journey so keep up the great work...
