both have been using weight machines without incident but would like to change up their routine but every time I try to incorporate a new free weigh lower body exercise they don’t want to do it for fear it will hurt their knees. They are doing the leg press, leg curl, leg extension machines now and have no problems. Are there lower body free weight exercises that do not include, squats, lunges, steps???
Walking is good exercise and ask if they ever take steps or go up and down curbs while carrying packages. Doing free weight exercise would make them stronger for ADL.
Walking over a step will work the lower body. If you get a doctor’s clearance for the exercises you suggest to the clients, that will help ease their minds and keep you safe.
