Started two weeks ago with the fundamentals and doing it just as a morning 30 routine along with basic warmups and kettlebell. Eager to get to the Foundation in a few weeks and considering diving into the Stretching right away. In addition I do once or twice a week minimal weightlifting (trying to push my 18% bodyfat down) - nothing crazy - about 40 mins. Also do some cardio 3-4 times a week: mountain biking, racquetball.
My question is how to prudently fit it all together and schedule it right? Time is a secondary factor. I may have some days when I have two activities: morning - GST and racquetball at the evening. I'm not familiar with intensity of the Stretching series or the Foundation. Can the former be considered a rest day? What are your thoughts?
