I recently started SFQ practice (level 1) and wanted to know when should I practice active exercises vs. sitting meditation ?

Is active exercises more for healing and sitting meditation more for prevention ? or are they both for same purpose ?

Also, how do I know when I am ready for level 2 ? (in other words, is it too early to study level 2 when one recently started level 1 and is working on improving one's own health ) - I would like if I can to assist in healing others.
