Sun Salutations can be difficult when you are a beginner but there are some tips my amazing teacher has shared with me that have been valuable to me and helped a lot. It's fun how sometimes just a small tiny modification can make things easier.
As my teacher always says in each and every practice "You must not suffer when practicing Ashtanga. You must feel that your body is working but not too much, you do not want to make your life harder than it already is, you want to make it easier and better. So bring your intelligence in the classroom and modify whatever asana you need to or rest in child's pose whenever appropriate".
