how many crunches a day to tighten belly
If a flat belly is your goal, situps may not be your best bet. By Yuri Elkaim, Contributor | Feb. 21, 2014, at 9:12 a.m. I am often asked if doing situps or crunches will get people the toned six-pack abs they're looking for. Unfortunately, even if you do 100 crunches a day, you won't lose the fat from your belly. Not a chance. And since a toned belly is exactly what everyone is looking for, the market is saturated with all kinds of belly-busting contraptions and workout DVDs.
