There are two videos in this post.
This video suits folks who are new to the studio and still getting their head around the fundamentals of safe squatting. Squatting is SUCH an important life skill, forget the times tables, if you can't squat right, you won't be able to sit into or get out of a chair, car, couch or onto a toilet. A lot of people have pain in their hips, back or knees when they squat and it is always a great relief for me as an instructor and for clients when thee simple principles help to reduce or remove that pain. NB: my clever use of white socks on a gray mat to highlight the alignment of my feet.
This next video is a little more detailed. The same fundamental principles apply, but here we introduce more details that will help to make the all important and often 'unfelt' gluten start to play a greater role in the squat action.
