Found this the other day RWdwpohh8X4 on youtube.
Has anyone used these and found them helpful? Is the heel raising beneficial? Any other exercises? My knees tend to audibly crack at the bottom of SLS. Not painful but I'd rather have it stop. Shoulder rehab has stopped my shoulders from cracking and I'm hoping these will have the same effect for my knees. Rolling on medicine balls and this omnimassage ball (hard, tennis ball sized massage ball) I have have helped somewhat but I'd like to do more.
Much thanks,
Johnny.
