I've started to experience a slight burning sensation in my knee over the patella after doing SLS. It is not painful, but it doesn't feel good either. I usually do SLS on Mondays and Friday for 3 sets of 3 reps 2s down 1s hold and 1s up. I usually do 15-20 hindu squats as a warm-up and am very cautious about exercises that I do on my knees (I always use padding).
What do you guys recommend?
