Hi guys,
I wonder if it's possible to use low intensity excercises from foundation that I've already mastered for a short cardio session, say 5x 15 deck squats plus Im or tuck ups plus Im. In the city where I live running in the winter oftentimes isn't a great idea so perhaps doing high rep deck squats or something similar from foundation twice a week might be a good substitute for running or cardio in general ?
Thank you
