Hi Everyone!

Welcome to day 3 of the New 30 Day Challenge! Today’s workout is focused on strengthening and toning your abs and arms, while incorporating fat burning cardiovascular movements. 

It’s a fun and challenging workout, and it only takes 20 minutes. I went through this workout 1X and paired it with a 3 mile run, but it can be done on it’s own and repeated up to 3X. 

I am off to work so I have to keep this short!

Don’t forget to check-in: on Facebook, Instagram or Twitter after you have completed the workout! 


30/50 Second Intervals

-Weights are optional. I use two dumbbells in this workout. I also use a jump rope, but rope less jumping or high knees can be substituted.

  1. Hi Melissa! I started following your workout towards the end of last year and so far I’m loving it! I started this challenge late so I did day 3 and 4 today. Totally killed me but still loving it! Thanks for all your great workouts!
