My partner has been dreaming of gaining mass. Last month he started to lift dumbbell every day. But, that was before we took a month of Christmas vacation to our hometown. Now that we are back, he loses his desire and becomes the lazy hubby. Sometimes I find him lifting the dumbbell but could not make even 10 rounds. I think it will be beneficial if he uses a supplement that doesn’t require him to lift weights. I searched the web and found NO2 Black. It will give the muscle that wants. I guess he will like the idea.
