Adwo,
In the Level One course the active exercises can be done in 35 minutes and the sitting meditation is 30 minutes. If I find my self running short of time I will do the sitting meditation as I drift off to sleep (lying down) and do the ending when I wake up in the morning.
The benefits I have received have been immense. As an older than 19 athlete, SFQ has helped me finally get over a reoccurring back injury and helps with all the little injuries that still occur.
