Thanks for your reply.
thats true what you are saying, but when the patient is elderly and with decresed muscles strenght of the legs, they usaly are puting a loths of effort to push with their arms and in the early after post cardiac surgery this could be contraindication. I know that Pt post cardiac ops should avoid lifting weight, but isn't it the body weight be quite a lot for some of the Pts?
I thought there have guidelines in week 1 for example what the Pts can or can not do, week 2, 3...etc.
