I have been walking on a treadmill everyday for about 3 months now, 1 mile a day at least. I just discovered that your workout is diminished if you are holding on. The treadmill makers probably won't tell you this for safety reasons but any able bodied person using a treadmill should not be holding on to the hand rails. Walking while holding on will not give you as good a workout and you will not burn as many calories. It is bad for your posture too. I had my suspisions but when I noticed that the trainers on "The Biggest Loser" won't let the contestants hold on I did my own research online. Anyway, today I walked my mile without holding on and it nearly kicked my butt! :faint: This infomation is given for those that do not already know. I wish someone had told me before! You might have to slow down some, I did, but you workout will become much more effective.
