a "quiet workout" - for those late night, last minute workouts. Or if your living in an apartment &/or have roommates/babies/toddlers you don't want to disturb
Quiet workout for early in the morning or late at night so you don't disturb anyone. One pinner said... "Since pinning this a month ago, I've done this workout 3-4 times a week. I am now 15 pounds lighter and 1 entire inch thinner. My name is Erika and I approve this workout."
