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???
To start from, I’d request a go-ahead from their GP and ask him/her what exercises he/she does NOT want me to do with them. Then, I’d surely not incorporate any knee-to-the-side motion (ouch!). Just like in case of the hip replacement, you do not want to cross your legs, right?… And so on… Good luck! 🙂
