My new year's goal is doing a hiit/strenght workout on every monday. So I've finished this workout today: https://www.fitnessblender.com/videos/hiit-cardio-and-butt-and-thigh-workout-hiit-and-strength

And oh my gosh, I was sweating like crazy. My legs will be sore for several days ^^

It really motivates me to have already finished the hardest workout of the week :)
