Im putting this in the general chat, as opposed to asking Shaun direct, just in case anyone else can benefit from the answer. My knees are shot to bits. I’ve had arthroscopies in both. The right, 9 years ago, was shown to have less than 10mm of cartilage left. The remaining cartilage looks like puff pastry and the end of my femur has grown into gap previously occupied by cartilage. As a result, and coupled with only having 1 hamstring, doing any exercise, balancing on one leg is mildly terrifying as my knees feel as if they are going to bend sideways. Doing these exercises 5 up 5 down only increases the feeling of instability. The goblet squat, which Im having to do with a weight plate held on my chest is fine. The Romanian deadlift and Bulgarian squat however are not. I have started cycling again to strengthen my legs and am slowly working to increase my time in the horse stance. QQQ Can I do barbell squats instead or perhaps use a Douglas squat circle or Kelso shrug bar, which I could easily fabricate.
