You can work biceps up to 1 day hard per week, and 1 day light-moderate per week for optimal muscle growth and recovery. Frugal Fitness World Wide Wellness Affordable Nutrition Home Workouts Healthy Recipes Bodybuilding.
An example would be run 1 day, bike another day, elliptical a 3rd day, and play basketball for an hour on a 4th day. Of course, I can not speak in behalf of all women, but personally, I like a nice, flat belly - doesn't have to be a whole six pack, but definitely not a beer belly, because it's a sign a man takes care of himself.
