Hi !!
Here is son information, it will also work out your abs.
“As you walk, contract your abdominal muscles for a count of 4 to 10, breathing normally and holding until the muscles fatigue. Release, then keep walking for 2 minutes without pulling in your stomach, and follow with another contraction. To practice finding and contracting your abdominals, stand with your back against a wall, fingers across your abdomen. Push your back into the wall and hold; you should feel the muscles contract under your fingers. When you can tighten them at will, you’re ready to incorporate an abdominal contraction into your walk. Over time, you should be able to maintain the contraction longer and longer. ” (From C:UsersJulietaDesktopEasy ways to get more out of your walking workout.mht)
Thank you !
