Hi Glynis. In my opinion whenever I have a client with exercise restrictions such as those given your client by her physician, I’m not sure that I would have them in a ‘group’ training environment. Whether or not a client has signed a waiver, and although their physician has ‘cleared them for exercise,’ the physician’s clearance was NOT without some restrictions. It’s difficult to truly monitor each participant’s participation in a group setting, and so monitoring someone with exercise restrictions would make them a one-on-on training candidate in my mind; particularly given the type of condition or injury that the client has, and the potential for a bad outcome if they are not properly monitored.
I hope that this helps.
