BRZUCH I BOCZKI 15 minut / Wyzwanie 10-dniowe / Monika Kołakowska

The penultimate workout in our challenge is a 15-minute set of abdominal and flank exercises. We have 9 exercises performed for 40 seconds. To complete the workout, all you need is a mat. The 10-Day Challenge is a daily dose of short and intense training! December is a very busy month for all of us, so a short, regular workout will help us de-stress, get moving, and boost our metabolism ;) 10 days = 10 workouts. #abworkout
