I had been looking for some time for a "leg strengthening machine" after a couple of lengthy spells in hospital. However as I studied the info supplied with EACH machine I realised I couldn't have one because I have a pacemaker fitted and none of the machines were compatible with that. None.
Then a few months later I came across the Legex SitWalk Exerciser which said it WAS compatible!
Have enjoyed using it for the required 20 movements per session daily. I can certainly feel a difference in my calfs, which DO feel they are getting stronger daily.
Although it's a fairly large machine, it IS very sturdy but easy to handle and use.
I have NO hesitation in recommending the LEGEX exerciser to anyone. Absolutely First Class!!
