Re: A Manual Treadmill.
I use both at my gym. I agree, walking on it is fine and does the job. But running is strange and you look a bit awkward until you get used to it. Though I fatigued much quicker on the manual than the power unit, the electric one is a piece of cake and I can walk at 5mph for 60 minutes no problem, that same workout on the manual is TORTURE towards the end.
