It’s important that all free workout routines you use include a program for strengthening your abdominals.  The abs is sometimes overlooked as an important muscle to overall strength.  Of course many like to build and rip their abs for appearance purposes however; the core has much more importance to muscular strength.  The abs assist in almost every single weight lifting exercise as it’s used to balance and gain leverage into lifting weights.  With those benefits, it makes it much easier to obtain the results you want.  So if your free workout routine doesn’t have solid abdominal programs, it’s time to move on.
