A question about the deck squat. I've been doing these for a while now and am up to step 7 with no major issues. Today, however, I found that the front of the knee near to the patellar tendon felt sort of stiff and achy after my last set. As a precursor, my knees are quite noisy during this exercise. It's usually nothing painful and hasn't caused any alarm, however, after the achiness in the front of the knee today it got me to wondering. How should I regress these to better handle the issue?
Further liner notes, my ankles are tight (so I cannot yet bring my butt to my Achilles or my calves). I cannot then keep my knees touching during the ascent from supine to standing because of this ankle tightness (I read elsewhere that for the deck squat to be passable/mastered, the knees only need to be shoulder width or narrower, which they are; but when having my feet/knees touching my knees splay outwards on the ascent because of ankle tightness).
Currently, my knees don't hurt but I don't want this to turn into something that hinders my training (as Coach says it's always better to address signs of an impending injury first and miss a day or two than to train on it, injure yourself and miss six weeks). I've ordered some gym mats (FINALLY), so I will intend to stack those and slowly decrease the height until I'm back on the floor. But should I focus on anything else in the meantime? Keeping feet/knees together? Only going as deep as to not experience any noise in the knee?
I'm only asking all of this because prior to today it hadn't been of any concern to me and my major issue was the IM (skier squats), which I'm also curious about. Should I simply keep working these daily? Because thus far they haven't improved much, meanwhile I have practically achieved full ROM on swivel hips, it seems, by simply doing them during my daily limber and warm up.
Any and all insights into deck and skier squats is appreciated
